Whenever I square a negative number its gives me a negative answer. For example -2 squared equals a positve 4, but it gives me -4. Is there a way to change the settings so that I will receive accurate answers to 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!

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 .
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
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...
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.
If you want the answer in rectangular form, set MODE a+bi and tap ENTER and QUIT. Tap square root sign, tap (-)4 and close the parenthesis and tap ENTER. The answer is shown as 2i.
If you want the answer in polar form, set MODE to re^xi and and DEGREE. Tap ENTER and QUIT. Tap the square root sign, tap (-)4, close the parenthesis, and tap ENTER. The answer shown is 2e^90i. (2 at ninety degrees). If you selected RADIAN mode, the answer would be 2e^1.57i (2 at 1.57 radians; or 2 at pi/2 radians)
