Question

A) (-15) +3-(18+12/6+4)=
b){(-1)+[3×(3+4/4)]} =
C)22-[-(3×15-(-12)×(-3))]}

Answer 1

Resposta:

A) -36

b) 11

C) 31

Explicação:

A) (-15)+3-(18+12/6+4) =

-15+3-(18+2+4) =

-15+3-(20+4) =

-15+3-24 =

-12-24 =

-36

b) {(-1)+[3×(3+4/4)]} =

{-1+[3×(3+1)]} =

{-1+[3×4]} =

{-1+12} =

11

C) 22-[-(3×15-(-12)×(-3))] =

22-[-(45-(-12)×(-3))] =

22-[-(45-36)] =

22-[-9] =

22+9 =

31
