Answer 1

Resposta:

Explicação passo-a-passo:

a) 10-8+15 = 2+15 = 17

b) 12+(35-12+2) = 12 +25=37

c) ((18+6):8+15):6

(24:8+15):6 = 3+15:6 = 18:6= 3

d) 37+(-25 -(4))

37+(-25-4) = 37-29 = 8

e)60:(2x(-7+18:(9))) -(-21+9+1)

60:( 2x(-7+2)) -(-11)

60:(2x (-5) +11

60: (-10) +11

-6+11= 5

f) -8+(-5+((-5)+(25))-10)

-8 +(-5+20-10)

-8+5 = -3

g) 3-(2+(-4) -(5+(-2))+8)

3-(-2) -(11)

3+2-11= -6

h)

(-1 +( 22-30)): (-3) +1

-1-8 :(-3) +1

-9 : (-3) +1

3+1 =4
