# Invalid computation Hello, I am taking an accounting course and purchased the Sharp EL-738 Business/Financial Calculator. The question that I'm trying to answer involves finding the present value of an annuity. When I enter the date quarterly compounding periods = 4 P/Y 4 year investment n=4 interest rate = 14 I/Y payment = 4000 PMT future value = 64000 FV and then enter COMP PV, I get a number that doesn't match what it is supposed to which is \$50,069.?? Can you tell me if I'm entering the data incorrectly please ie. the values should all be negatives?? I've tried a variety of things inlcuding the step by step instructions in the manual but nothing seems to work. Thanks.

I ordered the sharp EL-733A & was told by the vendor thath the model got replaced by EL-738. I cannot figure out how to use it as my course teaches the step by step with the 733 & none ot the keys are the same & some features are not available on my 738.

Help.......

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?

If you are talking about the multiplication sign, look for a key marked with a cross. It should be in the same column as the other operations, between the subtraction (-) and the division keys.

### How do you raise to a power on a Sharp el-738 business calculato?

I don't know about this specific calculator, but there is probably a button on your calculator that has a "y" with an "x" as a superscript (exponent). Or is could be reversed. But you wanted 2^8, you would push the 2 first, then the exponent button, then the 8, and there's your answer.

Good luck.
