Question

ola preciso resolver as expressoes numericas
a: -{-12-(+64)-[-2+5*(-3+9)}]
b: {-20+(+8)-[-7+9-(-1+5)]-(-1)}
c: {12-(+16)-[+5-(-2+13)]-(-5+3)}
d: -7[8+(-6-9)/3+2]*2+1
e: [(2+2*3)-32]/4-9

Answer 1

A)-{-12-(+64)-[-2+5×(-3+9)]}
-{-12-64-[-2+5×6]}
-{-12-64-[3×6]}
-{-12-64-18}
-{-76-18}
-{-94}
94

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

c: {12-(+16)-[+5-(-2+13)]-(-5+3)}
{12-16-[+5+11]-(-2)}
{12-16-16+2}
{-4-16+2}
{-20+2}
-18

d: -7[8+(-6-9)/3+2]*2+1
-7[8-15÷3+2]×2+1
-7[8-5+2]×2+1
-7[3+2]×2+1
-7+5×2+1
-2×2+1
-4+1
-3

e: [(2+2*3)-32]/4-9
[(4×3)-32]÷4-9
[12-32]÷4-9
-20÷4-9
-5-9
-14
