TI-83 Plus No Longer Squares Correctly

My calculator squares negative numbers incorrectly. When I enter "-2" and square it, the calcular answers "-4." Is there any way to fix this without having to reset my calculator?

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
