You must put all negative numbers in Parenthesis otherwise your calculator is not squaring the negative .

SOURCE: Negative exponents?

You entered it correctly. Although you can leave out the parentheses if you want. The calculator will do exponents before it does multiplication or division just like it does multiplication and division before it does addition and subtraction. It has a built in order for hierarchy of operations. You only need to use parentheses if you want to do something that is different from this order. FYI, dividing by a negative exponent is the same as multiplying by a positive exponent. You could enter it in either way. .825/10^-3 = .825*10^3 = 825. I hope this helps you out.

Press [2nd][,] to activate (EE) which appears on screen as a lower case E, enter the change sign (-) right of the [dot] on the bottom row of keys, enter the value of the exponent.
Ex: Enter Avogadro's number of Generalk Chemistry fame
6.02[SHIFT][,] (EE) (-)23
Here is screen capture of what it will look like.

I think what you did was use the minus sign instead of the negative sign, on that calculator, the two are not interchangeable. I purposely used the minus sign just now and also got a syntax error, but it looks like it works with the negative sign (-) located under the 3 button.

### How do i get a negative exponent?

I don't have this calculator, but let's give this a shot and see if it gives us the correct answer.

Let's try 10 to the exponent -2. The rule for negative exponents is to put 1 on the top and the term with a positive exponent on the bottom. In this case, it would be 1 on the top and 10 to the exponent 2 on the bottom, or 1 / 100 or 0.01.

In the calculator, enter 10, hit the x to the power of y key, left bracket (, the negative key (-), 2, the right bracket ), and finally the = key. You might not have to enter the left and right brackets, but I like to enter them to understand what I enter in brackets is the exponent.

Let me know if it works and if you have any other questions.

Good luck.

### How do i enter an exponent for ti-30xiis

Exponents of 10 are entered by pressing [2nd][X^-1] (EE).
For powers of any base, enter the base, press the [^] (below PI) then enter exponent. Use the (-) white key if exponent is negative.

### How to solve an equation with negative exponent

You probably want to calculate the numerical value of some mathematical expression with numbers raised to negative exponents.
Just enter the expression as you would with positive exponents Except that before entering the value of an exponent press the change sign key, marked (-), or +/- or (+/-). Do not confuse the change sign with the usual minus sign, which is usually displayed bigger then the change sign. Make sure that the (-) is displayed before the value of the exponent. Use parentheses if necessary.

### How to use it for exponents?

To enter exponents (1, 2, 3, -3..) use the general power key marked with Y^x or X^y or ^. Enter the base press the general power key then the exponent. If exponent is negative try enclosing it in parentheses. use the change sign key (-) to enter the negative sign before the exponent.
To enter power of 10, you can use the shortcut key marked Exp (the 10 must not appear when the Exp is used to enter exponents for power of 10).

### How do I use a negative exponent when working working with natural exponential functions, on this calculator?

The same way you'd work with positive exponents. The only difference is that a negative exponent has a negative sign, entered with the (-) key just to the right of the decimal point.

The (-) is used to enter negative numbers, not just exponents. The - key is used to subract one value from another.

### Whenever I type in a negative number raised to an exponent, the calculator outputs a negative number! even for a question like -2^2. How do I fix this?

You're not raising a negative number to an exponent, you're negating a number raised to an exponent.

If you want to raise -2 to the second power, you need to enter it as
( (-) 2 ) ^ 2

Without the parens, what you're getting is the equivalent of -(2^x)

### How do i input a negative exponent on my ti30x IIs

Use the EE (enter exponent) key (2nd-shift of the key just above the 7) to enter the exponent. Use the (-) key just to the right of the decimal point to enter a negative number.

The - key subtracts one number from another. The (-) key enters a negative number.

### 1.19x10-4=?

From page 16:
To enter a number in scientific notation:
1) Enter up to 10 digits for the base (mantissa). If negative, press the +/- key. (The key has two curvy arrows between the + and - but I can't do that on my keyboard.)
2) Press the EE key.
3) Enter a 1 or 2-digit exponent. If negative, press +/- either before or after entering exponent.

They give the example 1.2345 +/- EE +/- 65 which would display -1.2345 -65.
