quero com calculo

Answer 1

a) 50 - 25 x 2 =?
50-50=0

b) 30 + 8 ÷ (-2) =?
30-4=26

c) 15 ÷ 5 - 10 =?
3-10=-7

d) 3 + 6 x 2 - 15 ÷ ( -3 ) =?
3+12+5=20

e) [4-[2x(8-12)]÷2] =?
{4-[2×(-4)]÷2
{4-(-8)÷2}
{4-(-4)}
{4+4}=8

f) [2+[3÷(10-11)×1]÷21} =?
Não sei

g) 5×[(8-5) x (2+7)]
5×[3×9]
5×27=135

h) [[(8+4)÷3]x(3-1)]
{[12÷3]×2}
{4x2}=8
