Question

2- Determine o valor de cada expressão
a) 6+[12-(18:3+2)+5] =

b) 25-[10-(3x2+2)] =

c) 50-[15+(5x2-1)+3] =

d) 35+[(8x5-10:2)+(18:6-2)] =

Answer 1

Resposta:

a)6+[12-(18:3+2)+5] =

6+[12-(6+2)+6]=

6+[12-(8)+6]=

6+[4+6]=

6+[10]=

16

b)25-[10-(3x2+2)] =

25-[10-(6+2)]=

25-[10-(8)]=

25-[2]=23

c)50-[15+(5x2-1)+3] =

50-[15+(10-1)+3]=

50-[15+(9)+3]=

50-[24+3]=

50-[27]=

23

d)35+[(8x5-10:2)+(18:6-2)] =

35+[(40-5)+(3-2)]=

35+[35+1]=

35+36=
