Question

qual o valor de a+b+c ,sabendo que :a = (-1²), b = -1² e c = +1² ? ​

Answer 1

$\large{a)( - 1^{2} ) {}^{} } = \large \boxed{ \: \red{-1 \: }}$

$\large{b) - 1 {}^{2} } = \large \boxed{ \red{ - 1}}$

$\large{c) + 1 {}^{2} } = \large \boxed{ \: \red{1} \: }$

________________________________

A + B + C =

$\large{-1 + ( - 1) + 1} \\ \large-1+0 \\ \ \large \boxed{ \: \red{-1} \: }$
