Question about Casio FX-115MS Scientific Calculator

I am trying to calculate future and present value on my scientific calculator. Please help

The calculator does not have a TVM application, so you cannot perform these calculations.

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

SOURCE: how to calculate log value in calculator with different base value

In any scientific calculator log2(n) can be calculated with either ln or log function as
follows

Log2(n)= ln(n) / ln(2)

Or

Log2(n)=log(n) / log(2)

both will give nearly the same answers

This will show you how to do statistics (calculate average, standard deviation, regressions etc.) as to the mode and median refer to the definitions.

TO COMPUTE STANDARD DEVIATION AND 2-VAR STATISTICS.

I assume
you
know the theory. I will show you the key strokes

For
1-Var statistics

Press [MODE][3:STAT] [1:1-VAR].
You are ready to
enter values in the X column.

Enter a number and press [=]. Cursor
jumps to second number to enter.

Keep entering numbers and pressing
[=] till all numbers are in. Press the [=] key after the
last one.**Press
[AC] key to clear the screen.**

Press
[SHIFT] [STAT] (above digit 1.) then [5:Var]. Screen displays the
statistical variables 1:n ;2: x bar; 3: x sigma n; 4:x sigma n-1.

Press
the
number corresponding to the statistical value you want, ex 1:n . The
variable appears on screen. Press [=] and it will be displayed.

To
display another variable press [SHIFT][STAT][5:Var][ 1,2, 3, or 4] .

To access the sum of squares sigma x^2 and the sum of data sigma x
press[SHIFT][STAT][4:SUM] then [1: for sigma x^2] or [2: for sigma x].
Press [SHIFT][STAT][6:MinMax] to access minX and maxX.

For 2-var statistics

To
perform
2 variable statistics you press [MODE][3:STAT] and any of the
other regression options (except 1:1-Var). A two column template opens
where you enter the X and Y values. When finished entering data, press
[SHIFT][STAT][5:Var]. to access the different statistics. As I assumed
above, you should be able to
recognize what each variable means.

NPV stands for Net Present Value. Using this scientific calculator, you must utilize a formula to calculate net present value.

For example, if we want to find out what the net present value of $10,000 is using a 4% annual interest rate for 10 years. In other words, what amount do we have to invest today for 10 years assuming we get a 4% annual interest rate.

NPV=10,000(1+0.04)^-10

To do the exponent, use the ^ key.

Good luck.

Hi there, if you are following the example from page 24 of the manual - The steps are as follows - reset or clear the previous values by pressing the orange key (2nd F) and MODE.

Then make sure that BGN is not displayed (To do this press 2nd F and FV (above it you will see BGN/END)). To set the number of payments per year press 2nd F I/Y (above it is P/Y). Type in 12 and press ENT. Press the down arrow key and to make sure C/Y also says 12 (12 compounding periods per year). Then press on. Calculate the total number of payments - to do this type in 20 2nd F N (to get xP/Y) and then store the answer in N by pressing N again. (Your screen should say ANS -> 240.00)Type in your present value 56000 and press PV to store it. Enter the monthly payment press +/- 440 PMT. Enter your future value (press 0 then FV). Now to calculate the interest rate press COMP I/Y. It should give you 7.17 %

A very common error is not pressing N to store the number of total payments into the calculator.

If this is not the example you meant, please let me know - and I will explain the other example.

good luck

Hi there,

To calculate present value you need to type in all the other missing values and then press COMP and PV.

For example: if the future value is R5000, the interest is 12% p.a. compounded monthly and it paid over 3 years.

Type in 5000 and press FV

type in 12 and I/Y

Press 2nd F and I/Y and make sure P/Y says 12 (for 12 payments per year).

Press ON

press 3 press 2nd F N and then press N again (for 36 payments in total). Make sure your screen says ANS -> N otherwise the calculation will not work.

Now if if your payments are 0 (in other words you are not making monthly payments) then press 0 and PMT,

Otherwise, if you are making monthly payments for e.g. R200 a month, type in +/- 200 PMT.

Now calculate your original amount by pressing COMP PV.

If you made no payments your original amount should be -3494.62

And if you chose to add payments your original amount should be

2 526.88.

Google translated the heading of you question as **Referenc(es)**ing** algebraic variables.**

Some Scientific calculators have a few memory locations called a, b, c, d, M, x and y. M is the continuous memory while the others are variables where you can store values in view of some future calculations. These are usually accessed with** STO> key + Letter **name to store the values and **RCL + letter name** to recall the values to the command line. The values are fixed to 0 by default or to the last values stored in the named memory locations. **However the calculators do not handle algebra, unless they have a COMPUTER ALGEBRA SYSTEM or CAS.** Only some graphing calculators have that capability.

The first step would be to determine the rest of the problem. What's the future value? How long? Are there any payments? If so, how much and how often?

Asking for the present value of 20% is like asking "how do I get to the store?" Which store? From where? Are you driving, walking, riding a bike, or something else?

There isn't one. The TI 30 is a scientific calculator. The cash flow functions are usually limited to the financial calculators such as the TI BAII.

Hmmm, I don't think the problem is with your calculator. I'd be checking the accounting question again as I don't think you've got your annuity question structured right.

4 Year Annuity

14% Annual Interest Rate

Your contributing $4,000 per year over the next 4 years

and you already know the future value is $50,069?

You'd have to make annual payments of $11,878.93 (4 of them) at that annual interest rate to get to a future value of $50,069 (which has a present value of $43,632.24).

Are you sure that the FV isn't the trade in value at the end of the 4 years?
