Question about Texas Instruments TI34 Calculator

# How do I enter the future value for ordinary annuity formula into the TI-34 calculator?

I have to enter a formula with parenthesis inside of parenthesis. How do I do that on a TI-34 calculator to solve the formula for finding the future value of ordinary annuities?

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.
New users get to try the service completely Free afterwhich it costs \$6 per call and covers almost anything you can think of (from cars to computers, handyman, and even drones).
Goodluck!

It's giving you the correct answer for the problem you've input. When you specified 1 for n, you told it one month. If you specify more digits, you'll see that the answer is 1.00833333.

By default, the calculator works with annual interest rates but counts periods in months.

Viola. The initials TVM stand for Time-Value-Money; it's a widely used tool throughout financial mathematics. If you are looking to deal with annuities, bonds, present value equations, future value equations, or even certain stocks then you will want to use the TVM app within your TI-84.

When you go into that menu screen you will see about 10 input lines; and despite how you're being taught you'd be best off using only five (from a mathematical & conceptual standpoint). The backbone of the TVM is the time-zero equation of value. So, all you want to be touching is the N, I/Y, PV, PMT, and FV keys.

Background on TVM:
N = Number of intervals
I/Y = Effective Interest Rate Per Interval (5% is .05 but the computer wants it entered as 5.0)
PV = The Present Value
PMT = Recurring Payment (either deposit or withdrawal)
FV = Future Value

There are like 3 other inputs that I encourage you to ignore (in exchange for learning exactly what's going on within this application).

NOTE: You MUST make your effective interest term match your number of intervals. For example, an annuity with monthly payments for 5 years with a monthly effective interest rate of 2% would need an N value of 60 (which is 12 months per year times 5 years for a total of 60 months).

There's more that could be said, but I think this should help you find the PV of an annuity.

### Where is log on a TI-83 graphing calculator?

The LOG command on a TI-83 calculator is located just to the left of the 7 button. In other words, starting from the bottom left key of the calculator (the ON button), as you move up, you will see the STO-> button, then the LN button, and then the LOG button.
To use the LOG command, you will press the LOG button. log( will appear. You will then enter the value of which you wish to take the logarithm and add the closing parenthesis ) and press ENTER.

### Is the calculator suppossed to have "DEG" in the bottom right hand corner? I am trying to enter the numbers for the compound interest formula and I keep getting "Syntax Error" Is it because of the...

The DEG indicator on the screen is a reminder to the user that the ANGLE unit is in degrees. You can change the angle unit to Radian or Grads. That does not have any incidence on other calculations. It only affects the computation of trigonometric functions : sine, cosine, tangent, arc cosine, arc sine and arctangent. So if you have syntax error in the calculation of the interest formula, I can assure you it has NOTHING to do with the angle unit.
I do not see the formula you are trying to use, so I cannot be sure what you are doing wrong.
1. Possible wrong usage of the regular minus sign instead of the change sign (-) or (+/-)
2. Missing right parenthesis
3. A right parenthesis is inserted at the wrong place.
4. Incorrect use of the power function
I suggest you write the correct formula on paper and enter it step by step. A step is defined by an operation: multiplication, division, power. Start with the content of parentheses and work toward the outside. The last result is always the one stored in Answer memory (Ans).

### How can i solve for 'e' on a ti-83 graphing calculater??

Hi,
I am not sure I understand what you mean. In mathematics, 'e' is a particular number called the base of the natural logarithm. Its approximate value can be displayed by a calculator by taking the exponential of 1. Since its value is 'known', what is there to solve for?

But if you want to calculate exponentials of numbers you press [2nd][LN](e^x) . The screen displays e^( . You enter a number, close the parenthesis and press [ENTER].

Hope it helps.
Thank you for using FixYa and for rating ths solution.

### Calculate future population

The formula for population growth is:
population * (annual growth rate ^ number of years)

6000000000 * (1.01^24) = 7618407891

To get your calculator to perfom the calculation, enter it in the following steps:
Type 6000000000
Press the multiply key
Press the ( key
Type 1.01
Press the yx key (located right above the divide key)
Type 24
Press the ) key
Press the = key

You can reuse this formula, substituting any values you wish for the current population, growth rate, and number of years.

### Invalid computation

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?
