when you type -2 imagine your calculator doing the equation: -1 x 2. The - sign actually stands for a -1 so when you do -2 squared your calculator is simply following order of operations. It first squares the 2 making it 4, then it multiplies the negative making it -4. In order to get around this you must use parenthese. (-2)^2.
Hope this helped

Are we discussing squares or square roots?
The square root is the 2nd function of the multiply key.
There is no square function on the keyboard. Instead, simply raise the number to the second power using the ^ key just above the divide.
