Question

EJEMPLO:
4 + 7 X 2 -5 = 3 + 6 – (2 X 3) + 12 ÷ 2 =
4 + 14 – 5 3 + 6 – 6 + 12 ÷ 2 =
18 – 5 3 + 6 – 6 + 6 =
13 9 – 6 + 6 =
3 + 6 =
9

a) 9 + (12 – 4) x 3 – (5 +4) = b) 3 – 2 + ( 5 x 4) =


c) 12 ÷ 3 x 5 + 12 = d) 5 – 3 + 3 x 4 ÷ 2 + 5=

e) 4 x 3 + ( 3 x 4 – 3) =
f) 4 + 15 + (15 – 4) x 3 = g) 8 x (6 – 6) x 4 + 12 =
h) 8 – 4 + (4 – 3 + 6) =
