T.V.M Solver Report
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
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

Here is how to put it into a TI-83 Plus: N: Number of total payments, I%: Annual Interest Rate, PV: Present Value,
Dec 9th, Book Report
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.
Examples
Question 1:
Put into the calculator in the TVM Solver
N = 10
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:
Put into calculator in the TVM Solver
N = 10 (10 years)
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.

Tuesday September 9th, 2008
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.

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
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.

Today we started off class with Mental Math. Yes my favorite( no i am just kidding it's not my favorite)
After MM Mr. Maksymchuk made us play a game called Count to 20.
Where we raced with Mr. Maksymchuk to get to 20 we could go up by 1 or 2 numbers. No one got it at first but there are a few tricks to the game. we learnt that if you can get to 2 its a better chance to win. There are other key numbers 2
5

17
20
We realized that its all about going up by 3's 1+2=3 ,2+1=3, 1+1+1=3
It was a bit confusing at first but once you get the Pattern it comes easier.

Selection Reflection on Non-Linear Functions
1. Quadratics
2. Cubics
3. Exponentials
We learned different terms such as vertex, axis of symmetry, parabola, maximum value, minimum value, and zero.
I understood quadratics and cubics, but exponentails was the one i did not get. After going to tutoring and the help from Mr. Max i started to understand it.
Exponentials had the formula y=a*b^x
Cubics had the formula y=_x^3
For the exam, I will have to go over exponentials and how to solve them using excel and other devices.

Non - Linear Functions
Tuesday, October 7, 2008
Selection Reflection
First off you need to know that a system is 2 or more equations being considered at the same time:
y=2x+5
y=-3x-1 <------ this is a system
You should also know the different types of systems and be able to tell the difference between them: consistent is when the equations cross, inconsistent is when the equations are parallel and dependant is when the the equations are directly on tip of each other.
The next thing you should know is how to solve these equations using both the algebraical methods, which are the substitution and the addition/subtraction methods and how to solve them non-algebraical methods which involve using either graphmatica or a graphing calculator.
The final thing we learned how to do is word problems which aren't all that hard if you don't have trouble turning the words into an equations.
I hope this helps me and all of you reading this on the exam.
Selection Reflection
First thing we learnt was THE SUBSTITUTION METHOD.
It wasn't to bad just need to go through the steps into finding out the equation. Remember to plug the answer back into the equation to find out if its right.
Second thing we learnt was LINEAR COMBINATION ( ADDITION SUBTRACTION METHOD).
Just need to remember to line them up and when to add and when to subtract.
Third thing we learnt was SYSTEM TYPES NAMES.
Consistent system( one unique ordered pair solution).
Inconsistent system(no solution).
Dependant system(infinitely many solutions, in ordered pair).
- Define two variables( linked some how).
- Create two equations using two Variables.
So.. that was all the different things we learnt in this unit. I understand it for the most part beside WORD PROBLEMS. Before the exam I really need to get a good understanding on how word problems really work and each steps. ReMeMbEr when using the calculator or graphmatic to check the answers to always explain the steeps you did while using the programs.
Selection Reflection
The first thing that we worked on was "Systems Of Linear Equations," we did alot of graphing for that with that Graphmatica program and using our Graphing calculators.
The next thing we learned was about was how to solve Linear Equations algebraically by a method called the "Substitution Method" which was pretty easy once you get to know how to do it correctly. Then Mr. Maksymchuk showed us another method called, "Addition/Subtraction" method which was alot quicker to solve problems with.
We learned about the names of the different systems, "Inconsistent," "Consistent," and "Dependant." Later on we started Accelerated Math, I found this alot easier to use because it was multiple choice xD. We learned about solving "Word Problems" and various ways to solve them, I wasn't so good at these "Word Problems" so I should look back on them, I don't know how to use that excel program for them either... All of the work we do on the computers and using graphing calculators is new to me because I never took a grade 10 Applied math course, I took grade 10 precalculus twice :P. I hope to do well in this class and pass it. I hope this post will help me in the future, when I look back on this. Yeah!!!
Selection Reflection
ex. y=2x+5
y=-3x-1 those two equations is a system.
We started on the Substitution Method. This method is where we have to substitute numbers in equations. I found this to be pretty easy and i enjoyed learning about it. I love solving equations and i found it to be interesting.
We then learned a different Method. The Addition/Subtraction Method. This is where you line up the variables and either subtract or add. I found this method to be very easy as well. I got it right away and i was happy that i didn't have any frustrating times with it.
Mr. Max explained both of these methods very well, and his notes helped me a lot. I also liked how we can chose what kind of method we liked best and not have to only learn one.
Mr. Max also taught us about System Types/Names.
Consistent System: One, unique ordered pair solution
Inconsistent System: No solutions
Dependent System: Infinitely many solutions in ordered pairs
After learning this we moved on to something that i don't even want to mention. I hated this part so much. I did not find this easy as i did with the methods that we learned first. This was called Word Problems. I did not get anything about this. I tried to get it when Mr. Max was teaching us, but it just didn't seem to go through my brain. He told us to look on the course work drive for some sample word problems that he did in the past. After i looked through those (quite a few times), i seemed to understand it a little bit more than i did before.
Here are the rules:
Define two variables(linked somehow)
Create two equations using the two variables
We also used graphmatica to figure out some problems and to check our answers.
We can either use our calculators or graphmatica to check our answers when we are finished a problem to make sure we got the right answer.
So for the exam, i will have to get a good understanding of Word Problems. I think if i look more on the course work drive and practice questions more i will be able to eventually get it! :).
Selection Reflection
Then we had moved on to the Substitution Method. There was two of them, the first one is Addition Substitution Method (ASM), and the second is Subtraction Substitution Method (SSM). I use these letters in the brackets so that I can remember them easier, and it really does help.
Then we moved on to the Word Problems.
So by posting this I shall look back in a little while and re-teach myself what I have already learned so when it comes to a test day or exam time I can go back to the questions from the begining of the semester.

So linear systems of equations, what have we learned? Well we have learned how to solve linear systems using algebra. Once we got that down we learned how to solve using the adding subtracting method. After that we could use our calculators and Graphmatica. Then we learnt about the different systems, dependent, inconsistent and, consistent.
After all of that we started on word problems. We learnt how to use Excel to help us find the answer the word problems, I cant fugue out how to get Excel to work. That's all that we have learnt about so far, I hope this helps.

Selecton Reflection (Oct.6)
After learning that with a few practices, we were taught how to solve using the algebraically method, which I had found made more sense and I could follow it easier. Definitely study both substitution and algebraically methods.
We went over a few tips and tricks, which helped out, and would be something good to read over before the exam. A good thing to remember through out the course would be the system types and names... I have a feeling that knowing those would help out with future graphing and etc.I feel that i will definately have to go over material again, especially the substitution method ( I still have trouble grasping that ) I hope things will get a little easier for the exam if I can take the time to try and figure out the sections that give me trouble.
Selection Reflection
Then we learned how to solve systems of linear equations. We then learned how to identify the different types of linear equations (Inconsistent, Dependent, Independent,Etc.), then we started on the substitution method.
