Calculator issue

Thanks Zac

Complex numbers have nothing to do with this question.

You have to write it like this in the calculator: (-5)^2

$${\left(-{\mathtt{5}}\right)}^{{\mathtt{2}}} = {\mathtt{25}}$$

If you simply type -5^2 it takes it as -(5^2)

$${\mathtt{\,-\,}}\left({{\mathtt{5}}}^{{\mathtt{2}}}\right) = -{\mathtt{25}}$$

have you ever heard of complex numbers ??? (i)^2=-1
