e (6+9).(32:4) me ajudem por favor ​

Answer 1

a) +3

[(18+3.2)÷8+5.3]÷6

[(24) : 8 + 15] : 6

[3 + 15] : 6

18 : 6 = +3

b) 0

(+2-3+1):(-2+2)

0 : 0 = 0

c) +8

37+[-25-(-11+19-4)]

37 + [-25 - (+4)]

37 + [-25 - 4]

37 + [-29]

37 - 29 = +8

d) -5

3-{2+(11-15)-(5+(-3+1)]+8}

3 - {2 + (-4) - [5 + (-2)] + 8}

3 - {2 - 4 - [5 - 2] + 8}

3 - {-2 - [+3] + 8}

3 - {-2 - 3 + 8}

3 - {- 5 + 8}

3 - {+8}

3 - 8 = -5

e) +120

(6+9).(32:4)

(15) * (8) = +120
