$(-1)^0$ , calculating zeroth power of a negative number

Question

I wish to calculate the zeroth power of a negative number

$(-1)^0 = (-1)^{2-2}$ =$\frac{(-1)^2}{(-1)^2} = 1$

But when I put it in a calculator, it comes out to be $-1$.

Answer 1

You wrote $-1^0$, so the calculator interpreted it as $-(1^0)$ and not as $(-1)^0$. Use parentheses.
