Question

-2+{-5-[-2-(-2/3)-3-(3-2)9)]+5}

Answer 1

Resolvendo:

$-2 + \{ -5 - [ -2 - (- \frac{2}{3} ) - 3 - (3 - 2)9] + 5 \} =$
$=-2 + \{ -5 - [ -2 - (- \frac{2}{3} ) - 3 - (1)9] + 5 \} =$
$=-2 + \{ - [ \frac{ -6 +2 - 9 - 27}{3} ] \} =$
$=-2 + \{ - [ \frac{ -40}{3} ] \} =$
$=-2 + \{ \frac{ 40}{3} \} =$
$= \frac{ -6+40}{3} = \frac{34}{3}$
