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

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.

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.

N= Total number of payment periods
I%= Annual interest rate
PV= Present Value
PMT= Payment amount
FV= Future value
P/Y= Number of payment periods per year
C/Y= Number f compoundings per year
PMT= Press END for ordinary annuity or, BEGIN for an annuity due

NOTE: Money spent will be entered as a negative, and money earned will be entered as a positive.

T.V.M Solver Report

www.rrsd.mb.ca/mci/dornn/Files/applied_30s/lesson%202%20-%20TVM%20Solver.doc

T.V.M Meaning Time Value Money, is used to find a missing variable on a calculator (TI-83+) for financial reasons; like time, interest rate, future value, etc.

N- Total number of payment periods
I%- Annual interest rate
PV- The present value, or known as a principal
PMT- Payment amount
FV-Future Value
P/Y- The number of payment periods per year
C/Y- The number of compounding periods per year

When describing, or referring to questions, if we hear the words *Positive Value* That simply indicates the amount of money earned and put into your account; Whereas if we hear the words, *Negative Value* It indicates the amount invested, or taken out of your account.

When Inputting data on a TI-83+, You put in all your information, then highlight your variable you are trying to solve, then press Alpha - Enter

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
PMT=END

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.
