Are you using the (-) key to enter negative exponents? The - key is for subtraction, the (-) key to the right of the decimal point is for negation.

Having gone over a month without a response to my query, I assume it was simply a matter of using (-) instead of -.

### How to enter exponents

If you mean an exponent of ten, use the EE function (the shifted function of the "," key, located just above the "7" key. For example, to enter 1.2 times ten to the negative 3, press 1 . 2 2ND [EE] (-) 3

To raise a number to an exponent, use the ^ key located just above the divide key. For example, to calculate 3 raised to the 4th, press 3 ^ 4 ENTER

### I have a TI-83 plus calculator. I put into the calculator 96-5.970 ^2 multiplied by 0.2723 and it gave me the answer 2.4507 ^E- 4 Is there anyway to get the answer to the decimal value instead of it...

2.4507E-4 is scientific notation for 2.4507 times ten to the minus 4, or .00024507.

Take the 2.4507 and move the decimal point, to the left if the exponent is negative, to the right if it is positive, the specified number of positions.

If the magnitude of the result is too small or too large, the calculator will automatically switch to scientific notation. Imagine a number that has more than 12 digits to the left of the decimal point. How is that going to fit onto the display? Or a number that is 0 followed by the decimal point followed by 12 0s and then some significant digits?

### I need to know how to enter anything above cube root into my TI-83.

1. Use the universal power key marked with [^].
2. To avoid problems if the exponent is an expression, enclose it in parentheses.
3. To enter any power type number^(exponent)
4. If exponent is negative use the (-) change sign key next to the dot, below the 3 key.
5. To calculate the roots (cubic, fourth, fifth, etc.) roots use the fact that a root of n-th order can be represented as ^(1/n)
6. Ex: cube root of 27: 27^(1/3); square root of 64 : 64^(1/2) or 64^(0.5)

### What button do I use to find negative log on my TI-83 calculator...also how do I put in a negative exponent?? i.e 1*10 to the negative 6th .....

You compute the negative of a logarithm the same way you compute the negative of anything else. However, do you really mean the antilog (inverse logarithm)? Use 2ND [e^x] for the natural antilog, 2ND [10^x] for the common antilog.

For negative exponents, as well as negative anything, use the (-) key next to the decimal point. For your example, 1 EE (-) 6

### Multiplying exponential numbers

I am needing to find out what key I can push for an exponent. I have an exponent that is 2520 and I dont know what button to push for it.

The problem is as follows:

3000 ( 1+ 0.06/360) exp.2520

3000 ( 1.000166667) exp. 2520

3000 - 4565.72

1565.72

Now how in the world did they get 4565.72. What buttons am I needing to push.

### TI-83 Plus No Longer Squares Correctly

when you type -2 imagine your calculator doing the equation: -1 x 2. The - sign actually stands for a -1 so when you do -2 squared your calculator is simply following order of operations. It first squares the 2 making it 4, then it multiplies the negative making it -4. In order to get around this you must use parenthese. (-2)^2.

Hope this helped
