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!

### I&#39;m using a Casio fx-83GT PLUS Which I got for Christmas but recently I&#39;ve noticed that when I do -2 to the power of 2 it gives me negative 4 rather than positive 4, is this a wrong s

The calculator is giving the correct result FOR THE PROBLEM YOU GAVE IT, not for the problem you meant to give it.

When you told it to calculate negative two to the second power, it calculates two to the second power, giving 4, then negates it, giving -4.

If you want to calculate the square of negative two, use parenthesis to tell the calculator that you want the negative to apply to the two and not to the result of the squaring.

### My TI84 plus silver edition calculator is giving me an incorrect sign whenever I do an exponential function. When I type in -25^2, it gives me -625 instead of 625. How do I fix this?

It's giving you the correct answer. It's calculating the negative of 25 squared. 25 squared is 625, and the negative of that is -625.

If you want to calculate the square of negative 25, you need to tell the calculator that.

No, you're not squaring a negative number, you're negating a square. When you press (-) 4 ^ 2 ENTER , the calculator is calculating -(4^2). 4^2 is 16, and the negative of that is -16. What you want to do is to calculate (-4)^2 by pressing ( (-) 4 ) ^ 2 ENTER .

You're not calculating the square of a negative number, you're calculating the negative of a square. You need to use parenthesis to indicate the square of a negative number.

### I cant figure out how to get the square root of a negative number

The square root of a negative number is an imaginary number, and the TI-30XA does not deal with imaginary numbers.

However, the square root of -x is equal to i times the square root of x. So, to calculate the square root of -4, for example, press 4 square_root = and read 2. Thus the square root of -4 is 2i.

### When i square a negative, i get a negative answer, how do i fix it so it gives me the positive number?

Actually, you're negating a square, not squaring a negative. When you put in -x^2, it's getting calculated as -(x^2). In order to square a negative number, use parentheses and calculate it as (-x)^2.

Also, make sure you're using the +- key to the right of th decimal point instead of the - key when entering the negative number.

### Hi, i have a casio fx-82au plus, and it gives me the wrong answer when i press -X^2(X is any number. it'll give me -X. how can i fix this??

If you want to square a negative number, you should enclose it in parentheses then raise it to the 2nd power.
-5^2 =-25 .Priority to squaring ahead of negating
(-5)^2=25 .Priority to parentheses before squaring

### How do you square a fraction with a negative number like (3/4)^-2

Place both the base and the exponent in parentheses

(3/4)^(-2) then press enter. Your answer will be in decimal form at first 1.777...

Press MATH
Select the 1: Fraction option and it will convert your decimal value to the fraction answer of 16/9.

Negative exponents flip the fraction. For instance, (3/4)^(-1) = 4/3. So for (3/4)^(-2) you could just square the numerator and denominator separately to get 9/16, and then flip the fraction to account for the negative. That will give you 16/9.
