Why does your calculator say negative 3 square equals negative 9?

Because it thinks that the negative sign is actually another operation to do and because of the order of operations, the calculator squares it first then makes it negative. To fix it, type it in like this (-3)2

How do you simplify the square root of -96?
In simple terms, negative numbers don't have square roots. If you multiply a number by itself, you can never get a negative number for the answer. Square a negative or a positive, you get a positive; square zero, you get zero.Now, if you get fancy, you could say that while a negative number has no real square roots, you can make one up by inventing the imaginary number i, which is the number that when squared, equals -1. Then you can say that sqrt (-96) = [ sqrt(-1) ] * [ (sqrt(96) ] = i*sqrt(96). From here, you can go ahead and simplify sqrt(96) ...Look for a perfect square factor, and take it out of the root: 96 = 4x24 = 4x4x6 = 16x6; sqrt(96) = sqrt(16)*sqrt(6) = 4sqrt(6).So sqrt(-96) = i*4sqrt(6), which is customarily written as 4isqrt6(You would write a radical sign wherever it says "sqrt" above.)

What is square root of 37?
The square root of 37 is the number which yields 37 when multiplied by itself. Since 6x6 is 36, the square root of 37 will be slightly higher than 6. A calculator will be necessary if you don't know the longhand method for finding square roots. This method is no longer taught in schools — suffice it to say, it's like long division, but more complicated. The answer is 6.0827625303.
