-(-12-(-8)²-[-2+5x(-3+9)]} R 104

{-20+(-7+9)³-[-7+9-(-1+5)]-(-1)³}

-5²+(-3)x(-1+7)-[+3-5x(-1+2)] R -41

Answer 1

a) {-(-12-(-8)²-[-2+5x(-3+9)]} = {-(-12)-(64)-[-2+5x6]} = {12-64-[-2+30]} =
= {-52 -[28]} = -80

b) {-20+(-7+9)³-[-7+9-(-1+5)]-(-1)³} = {-20 +(2)³-[2-(4)]-(-1)} = {-20+8-[-2]+1}
= {-12+2+1} = -10+1 = -9

c) -5²+(-3)x(-1+7)-[+3-5x(-1+2)] = 25 + 3x6 - [3-5x(1)] = 25 + 18 - [3-5] =
43 - [-2] = 43 + 2 = 45
