Question

15-(6-2)+(10-4)=
-105+(3×25)-12=
-8[-2-(-12)+3]=
25-{-2+[6+(-4-1)]}=
-4{2+[-3-(-1+7)]+2}=​

Answer 1

Resposta:

17

-42

-104

26

Explicação passo-a-passo:

15-(6-2)+(10-4) => 15-(4)+(6) = 15-4+6 = 17

-105+(3×25)-12 => -105+75-12 = -105+63 = -42

-8[-2-(-12)+3] => -8[-2+12+3] = -8[13] = -104

25-{-2+[6+(-4-1)]} => 25-{-2+[6+(-5)]} = 25-{-2+[1]} = 25-{-1} = 25+1 = 26
