I'm worried that this will be a spanner in the works when I'm using a calculator in an exam , I know that $-2^2= 4$ since $(-2) \cdot (-2) = 4 $. So why does my calculator show it as negative 4 ? Does anyone know if there is a way to reset my calculator so it doesn't do this? The make and model is Casio fx-83ES.

There is a difference between $-2^2$ and $(-2)^2$ In the first examples you square the number two and then you apply the negative. In the second example you sqaure the number negative two then you get the desired reuslt, 4
