Question 237328
I am assuming you did not lose any parentheses. So this has to do with order of operations.
{{{-2^2-(-2)^3}}} parentheses take precedence over everything and then exponents take precedence over multiplication and subtraction.
For the first term you square first and then multiply.
But for {{{(-2)^3}}} you have to cube {{{-2}}} before multiplying by -1.
So we have {{{-2*2-(-2)*(-2)*(-2)=-4-(-8)=-4+8=4}}}
