The negative sign is the same as the minus sign. It is above the [+] and below [x] . Using the minus button will have the same effect and will negate the number you press after it.

### Minus sign display problem

Calculators have two similar signs: the regular minus sign for subtraction, and the negation (change sign) sign. When applied, the latter changes the sign of the quantity to which it is applied. The minus sign - for subtraction is on the central line, the negation sign is smaller and somewhat raised above the center line.
The change sign key may be marked (-) , (+/-), or +/-

### Negative numbers

The plus sign in front of a number does not need to be written. However if the number is negative, the sign must be used. The calculators do have a key to make a number negative. It is usually marked as (-) where the negative sign - is than smaller the minus sign for the subtraction operation. On other calculators, the key is marked as +/-. You must be careful how to use it: it must be the first sign of any expression.

### I need to use the exponential function with a negative exponent on my TI-30XIIS. I hit 2nd then e^x button, but when i input a negative exponent I get an error. Help please!

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 ente 8x - 1 over 10 on my TI 84 plus silve edition

Hello,
I am not sure what the cross (x) means: is it a multiplication or the variable x, so I took a screen capture of both cases.

The top case is obtained as follows the asterisk is the multiplication sign to thr right of digit 9; the small minus is the change sign key the minus sign in parentheses under digit 3 and to the left of ENTER key.; the forward slash is the division sign, above the multiplication sign.
This small minus called change sign makes a positive number negative and a negative number positive, hence its name. If your expression starts with a negative sign that is the one to use. Use it also for negative exponents.

As you can see the result is -.8. Notice how the - before the dot is small with respect to the regular minus, as in the last expression.

For the last expression on the screen capture, there is nothing special, except that you have two ways to enter the variable X.

1. Press [ALPHA] [STO->]
2. Press the key [X,T, Theta, n] to the right of the green [ALPHA] key.

Hope it helps.

### Wrong answer with squared negatives.

Your calculator will square a number before it applies the negative sign, so what you're actually doing is squaring 2, then applying the - sign to your answer. You need to put the -2 in parenthesis, so (-2)^2. That will give you 4. Hope this helps!
