if you've touched polynomials ever, you'd expect the exponent to be before the negation. If you write x³-x² you don't mean x³ + (-x)² = x³+x², you mean x³-(x²)

I think they mean that you said the correct answer is -8 in your first comment. Typo?

I was taught that negative numbers should be written as (-2) with the parentheses when using exponents. So I assume that the calculators are doing it right, or maybe it's just a measure against calculators doing it wrong? I cannot be sure. Also-2 = 0-2 so -2^2 = 0-2^2.

No you misunderstand. I'm not talking about the negative. 2² = 4. But in your original comment you said -2² = -8 ? I think you meant -2² = -4

Oh, right. It should have been -4. Thanks.

My calculators have a separate sign button labeled "(–)"

Mine have it too, but it doesn't change the results.
