January 23rd/09

We had started off the class with mental math, then we handed the sheets in.We then worked on the Peer Evaluation Sheet that we had received a couple of days ago. We then worked on accelerated math for the rest of the class. Accelerated Math is due on Monday, so work hard and get as much as you can done

REMEMBER:

Sorry I missed my post yesterday, so i'm going to make up for it today. Ok, yesterday we couldn't go into Mr. Maks's class because he was having an exam for his grade 12 class I believe, so we went down to the caf. to do what ever work we had to do. We had a choice to either work on an old exam to practice for our exam next Tuesday, or we could work on accelerated math. Remember that we are allowed cheat sheets for the exam so get them do becauase they will help you. I think this is all I have to say for now, write you guys later.

january 19

Today, we started with mental math. after this Mr. Maksymchuck gave us the blog scribe names that we have to evaluate for. These are due for Monday the last day of classes. And the exam is also on Tuesday in room 204. tomorrow and wenesday we are supposed to go to the cafeteria a work period, due to a exam that will be taking place during the morning.

Jan 16

Today we took 25 minutes to do mental math and then it was a work period. The only other thing is that we need to go to the resource center or cafeteria on tuesday and wednesday next week.

Thursday, Jan 15/09

No school yesterday because the buses weren't running!

Circle Property #7/Jan 13/09

Exactly two weeks from today before exam!! Ugh..
First thing today Mr. Maxs went over the Exam Format. There will be two parts to the exam M/C and Long Answer.
After that he taught us the Final Circle Property #7 Circle Quadrilateral.
We did the same procedure as the last 6.
Just an reminder there is a lot of Accelerated Math that will be due
so don't forget!!!

Jan 12/09

This class, we did mental math and Mr. Maks notified us that he will only be seeing us on Monday and Friday next week, but will be available for breaks and lunch time if we have any trouble or questions. Mr.Maks then explained Formulas for interior angles, measuring a polygon. We made a spreadsheet in excel for finding an angle measurement in a regular polygon.
*** Remember*** exams in a couple weeks
Our math exam is
Tuesday, January 27 @ 9:00 in the morning in the classroom.

circle properties 4-6 jan 9

to day we started of with mental math, only 5 left!! then we did circle properties 4 through 6. then we got to work on accelerated math. hear is a vid on the notes we did to day.
Enjoy

January 8th, 2009

Today we started out with Mental Math, and then went on to learn about more Circle Properties and we used the program Euklid again.

Circle Property #2 - If an inscribed angle in a circle inetercepts semi-circle, then the angle is a right angle.

Circle Property #3 - If in a circle, an inscribed angle and a central angle both intercept the same arc, then the central angle measure is double the inscribed angle measure.

Today was just more fascinating stuff on circle properties.

Well... we had started the class off with mental math, right after we watched a video about budgeting. Then we moved on to a homework check for Exercise 2 and Exercise 3 on the budgeting and investments booklet that Mr. Max handed out last week. After the homework check we were able to work on the questions that we did not finish or we could have worked on accelerated math. We are able to scan and do accelerated math until Friday at 3:40, that is if there are normal classes in the after noon.

December 10

Well on the 10th we talked about simple interest vs. compound interest. We also learned how a bank uses and earns you money.

DECEMBER 11

Today, we started off with mental math. we had a long discussion on question 3 about how a fifth is equal to ten. After this we continued to go on with our work sheet that he gave us yesterday. we can do these sheet with a partner if you wish.

T.V.M Solver Book Report

The T.V.M. solver is based on the concept that an investor would rather receive a fixed amount of money today, opposed to getting that same amount of money on a future date. Basically the time value of money represents the interest you would earn on a payment received today, if held, earning interest, until that future date.

To open the T.V.M. solver on your calculator you simply need to prees [APPS], [ENTER], [ENTER] which will bring you to a screen with the following variables:
N: Number of compounding periods. Type this in as number of years times number of compounding periods per year.
I%: Interest rate. Type this in as a rate, NOT as a decimal.
PV: Previous Value. This is the starting value of the account. If it’s a loan, the amount will be positive, the amount you owe. If it’s a savings account, the amount will be negative, the amount you (take out of your pocket and) put in. If you don’t start the savings account with a deposit, this value will be zero.
PMT: Payment amount. Since this is coming out of your pocket, it’s negative. If you’ve started a savings account with a deposit, and don’t plan to make regular deposits, this will be zero.
FV: Future value. For savings, this will be the value after a given number of compounding periods. For a loan, this should be 0.
P/Y: Payments per year. This number should be the same as the next item, unless specified otherwise in the problem.
C/Y: Compounding periods per year. See above.
PMT: END BEGIN: Will the payments be due at the beginning or end of
the month.
__________________________________________________________________
EXAMPLE
1.) Now, suppose you are taking out a 5-year loan on $25000 at 6% annual interest compounded monthly and you want to know the monthly payment. Fill in the values on the TVM Solver screen as shown:
(Enter N as 5 years * 12 compounding periods per year)
N=60
I%=6
PV=25000
PMT=
FV=0
P/Y=12
C/Y=12
PMT=END

2.) Now, move the cursor to PMT, press the green ALPHA key, then ENTER.
Your payment will show up as a negative number (since it’s coming out of your
pocket):
N=60
I%=6
PV=25000
PMT=-483.32003...
FV=0
P/Y=12
C/Y=12
PMT=END
3.) Suppose you know you can afford a $250 per month payment on a 60 month loan at 6% annual interest compounded monthly. You can enter N as 60, since
they didn’t give you a number of years. Fill out the TVM Solver screen as
shown:
N=60
I%=6
PV=0
PMT=-250
FV=0
P/Y=12
C/Y=12
PMT=END
4.) To find how much you can afford to borrow, move the cursor to PV, press the
green ALPHA key, then ENTER. The amount you can afford to borrow is
shown:
N=60
I%=6
PV=12931.39019
PMT=-250
FV=0
P/Y=12
C/Y=12

TVM Solver

TVM stands for Time, Value, of Money. It is used to figure out budgets and future interest. It is a very useful tool for people wanting to retire early. It may be the key to buying that dream house. The way it works is it figures out just how much money you need to put away to increase interest and profitability.

Here is how to put it into a TI-83 Plus: N: Number of total payments, I%: Annual Interest Rate, PV: Present Value,

T.V.M Solver

The T.V.M is used to find a missing variable in interest rate, time, and future value. It is also used for financial calculations. Everything under “TVM Solver” is a function that does a calculation based of the values entered in the TVM Solver.

How to get to the T.V.M Solver in your calculator:
1. Turn on calculator
2. Press “Apps”
3. Press “Finance”
4. Press “TVM Solver”
The variables in the TVM Solver are:

N = # of years.

I% = The % interest (or discount if you’re receiving money you) you are expecting.

PV = Initial Investment (this number should be negative if you are investing, as you’re giving your investing your money).

FV = Future value

PMT = Number of payments per period (period set below).

P/Y = Periods per year (should generally be one).

BEGIN = You should have your Ti-83 be on “END” by default, but you will want to change it to begin when dealing with annuity due.

END = You want to have this set when dealing with ordinary annuity.
Examples

Question 1:

We want to invest $1000 today and want it to be $5000 10 years from now. What is the interest rate we need to accomplish this?

Put into the calculator in the TVM Solver

N = 10

I% = 0 (because we don’t know what the interest rate is)

PV = -1000 (negative 1000 because that’s how much we’re investing)

PMT = 0 (no additional payments being paid / period )

FV = 5000 (this is how much we want to have by the end of 10 years)

P/Y = 1
After entering that all in go:
“2nd”
“Mode”
(It will take you back to the display screen.)
Next, press
“Apps”
Finance”
“TVM_I% (that’s number 3)

Your result should be 17.46%

That all means that if you invest $ 1000 today and want $5000 in 10 years from now, the interest rate you must have is 17.46%.
Question 2:

What must I invest now at 8% to get $5000 10 years from now?
Put into calculator in the TVM Solver

N = 10 (10 years)

I% = 8 (enter whole numbers, TVM Solver converts it to .08 for you)

PV = 0 (0 because we want to know how much to invest to get $5000)

PMT = 0 (no additional payments being paid / period )

FV = 5000 (this is how much we want to have by the end of 10 years)

P /Y= 1
After that go:
“2nd”
“Mode”
(Takes you back to your display screen)
Next press
“Apps”
“Finance”
“TVM_PV” (that’s number 4)

Your result should be -2315.96
That all means that if you invested (your investing which is why it’s a negative) $2315.96 today at 8%, in 10 years you will have $5000.

TVM Solver

To use the T.V.M Solver, first press the "APPS" key then select "FINANCE" then go to "T.V.M Solver".

N: is the number of periods in the term of your investment, annuity, loan, etc.

I%: represents the rate of interest before adjustment for inflation for an investment, annuity, loan, etc.

PV: means the present value of the investment. Can be positive or negative. If it is positive it indicates the amount of money gained by the investment. If it is negative it indicates the amount of money lost or paid out to the investment.

PMT:represents the payment made to the investment or to pay for a loan.

FV: represents the future value of an investment after compounding period.

P/Y: represents the number of payments per year from an investment. Must be a positive integer.

Here are two options for no payment periods:

-Set "N" to years and P/Y=1

OR

-Set "N" to payment periods and P/Y=C/Y (Compounding periods per year)

"PMT: END BEGIN.": used to set the TVM Solver for 'ordinary' annuities, (END), or annuities 'due' (BEGIN).

Here are some examples:

For my References I used the following link: http://argyll.epsb.ca/jreed/calculator/ti83p/TVM.htm

The examples, screenshots, and pictures that I used are also from this site.

I also used wikipedia search to help understand some of the words I didn't know.

Tuesday September 9th, 2008

We did not do Mental Math today because Mr. Maksymchuk wanted to talk about the blog and the posts for the "Book Reports" on the T.V.M solver and give us more time for the Book Report posts. Mr. Maks talked about referencing the sources on the T.V.M solver and about plagiarism. Don't just copy and paste things into your blog, especially words you do not understand. Type it in your own words please.
In 1991, Mr. Maks talked about a student who cheated, the student had found a journal and wrote out a paper for an assignment and did not reference the sources, he was kicked out of University and banned from going to other universities for a while. Plagiarism in high school wouldn't result in such a punishment of getting kicked out and banned from schools, it just goes to show that you shouldn't copy anyone elses work without referencing it first. An assignment in high school that is plagiarized will result in a 0 mark on that assignment. The Internet is a great source for information and is greatly used today. Please do not plagiarize!


With great power comes great responsibility. - Uncle Ben Parker, from the 1st Spiderman Movie!

We have until the end of today to work on the "Book Reports" and post them to the blog.
Budget things can still be checked by Mr. Maks, etc.
Mr. Maksymchuk put on some Christmas songs on for us to enjoy. I found the music annoying, sounds like some old Fuedal era music... Well not anymore, thats good.
8 More classes left until Christmas break.
16 Days until Christmas from today! Yeah!!!!

T.V.M solver

T.V.M solver is designed to help you solve problems that in valve money growing at a predetermined interest rate over a set amount of time.
To get to T.V.M Solver you go to apps then to financial then choose T.V.M Solver. Now that we can get their let’s get down to business. Here is an example. So you have $100 that you are going to invest at 10% a year for 5 years.

PV Present value $100

F/V future value

N is the number of years 5

I is the interest rate 10%

P/Y payments per year 1

C/P compound per year 1

Pmt amount of money invested per year 0

When you have all the data in you go down to FV (future value) and press alpha enter. That will give you the answer which should be $161.05.

hear is another example of how to solve for n:

Imagine that you have just retired, and that you have a nest egg of $1,000,000. This is the amount that you will be drawing down for the rest of your life. If you expect to earn 6% per year on average and withdraw $70,000 per year, how long will it take to burn through your nest egg (in other words, for how long can you afford to live)? Assume that your first withdrawal will occur one year from today (End Mode).

P/V=-1000000

F/V=0

N=

I%=6

P/Y=0

C/P=0

PTM=70000

Now you can go to N and and solve by pressing alpha enter and that should give u 33.39 witch is how long you Can live for off of the $1000000.

Book Report: T.V.M. Solver

Thanks to the internet, this book report will tell you on how to access the T.V.M. on your calculator and give you some examples.

T.V.M stands for Time Value of Money. TVM is based on the idea that money received earlier is worth more than the same amount of money received later.

To get to the T.V.M. solver on your calculator, you press APPS, ENTER, ENTER, and you will get to a screen which shows these following variables:

N= total number of payments
I%= nominal interest rate, expressed as a percent (use 5, for 5%, NOT 0.05)
PV= present value or principal
PMT= amount of each payment (for mortgages and annuities)
FV= future value
P/Y= payments per year
C/Y= compounding periods per year

Here are examples to represent both algebraic and TVM Solver solutions:

1.Solving for Future value: If you deposit $2500 in an account earning 12% interest compounded weekly, how much is it worth in 4 years?
N= 4
I%= 12
PV= 2500
PMT= 0
FV=
P/Y= 1
C/Y= 52

After you have filled in all the numbers, move your curser to FV= and press ALPHA SOLVE (enter) and the number 4037.95 should show up where the FV= is. That’s the final answer for this question.

2.SSolving for present value: How much money must you deposit now, if you need $10000 in 4 years, and can earn 5.5% interest compounded monthly?

Now, we bring up the TVM Solver, set..
N = 4,
I% = 5.5,
PV =
PMT = 0,
FV = 10000,
P/Y = 1,
C/Y = 12.

Move to the present value line and press ALPHA SOLVE (enter). The answer is -8029.22 (the answer is negative, because you have to deposit that amount).

How long does it take $5000 at 8% interest compounded daily to reach a value of $7500?
N =
I% = 8
PV = 5000
PMT = 0
FV = 7500
P/Y = 1
C/Y = 365

Move the cursor to the line for N and press ALPHA SOLVE (enter) to get the answer.

Book report, T.V.M. solver

With the help of my trusty internet friend, I have found that the T.V.M. solver (Time value of money) functions to analyze financial instruments, such as loans, mortgages, leases and savings.
To get to the T.V.M. solver on your calculator, hit "apps" then "finance" and that leads you right to the "t.v.m. solver"

Now you need to fill in the blanks on your calculator, but before you can do that you need to know what the letter symbols beside each blank means.
N= The number of payment periods
I%= The interest rate
PV= Present value
PMT= Payment amount
FV= Future value
P/Y= Payments per year
C/Y= Compounding periods per year

(remeber to ender cash inflows as positive numbers, and cash outflows as negative numbers)

Examples:
Financing a car.
You have found a car you would like to buy. The car costs $9,000. You can afford payments of $250 per month for four years. What annual percentage rate (APR) will make it possible for you to afford the car?

Enter the T.V.M. solver
Enter known values:
N=48;
PV=9000;
PMT=M250 (Negation indicates cash outflow.);
FV=0;
PpY=12 (computes an annual percentage rate);
CpY=12;
PMT=END.

Example 2
Calculaing interest on a fixed payment.
At what annual interest rate, compounded monthly, will $1,250 accumulate to $2,000 in 7 years?

Enter the T.V.M solver.
Enter known values:
N=7;
PV=M1250 (Negation indicates cash outflow or investment.);
PMT=0;
FV=2000 (future value is cash inflow or return);
PpY=1;
CpY=12;
PMT=END.
Place the cursor on the I% prompt and solve to get your interest rate.

Here is my T.V.M solver Book Report

The T.V.M solver works by filling in the missing variables of finance. There are 8 variables that are associated with this program. Next I will explain what each of the variables mean.

N: represents investement and annuity or loans.

I%: it will also be a positive integer, represents the "normal rate" of the investiment and annuity or loan. it is always writen as a percent instead of a decimal or a fraction.

PV: represents the " present value" of the investiment and annutiy or loan.

PMT: represents a payment that is used to pay off a loan or make an annuity.

FV: it represents " future value" for an investiment, annuity or a loan after the N compounds have passed.

P/Y: represents the payment of a loan or annuities for one year.

C/Y: represents the compounding period year after year.

PMT:END BEGIN, this allows the user to set the TVM solver for " ordinary annuities, ( END), or anuities 'due' ( BEGIN)
