Respuesta:
1. [(40 = 4)-(14 – 2)] + (8 = 2) = 2
[(40 = 4)-(14 – 2)] + (8 = 2)
[10-12] + 4
-2 + 4
2
2. [(9 x 4) = 6 - (4 x 2)] = -2
[(9 x 4) = 6 - (4 x 2)]
[36 = 6 - 8]
[6-8]
-2
3. (8 x 3) = (6 x 4) = 1
(8 x 3) = (6 x 4)
24 = 24
1
4. (6 x 3) + [4– 3 x 2 + (4 + 2)] - (54 = 3) + (2 x 3) = 10
(6 x 3) + [4– 3 x 2 + (4 + 2)] - (54 = 3) + (2 x 3)
18 + [4– 3 x 2 + 6] - 18 + 6
18 + [4– 6 + 6] - 18 + 6
18 + 4 - 18 + 6
22 - 18 + 6
4 + 6
10
5. (24 - 12) = 2 = 6
(24 - 12) = 2
12 = 2
6
6. (14 - 8) - (29 - 19) =
(14 - 8) - (29 - 19)
6 - 10
-4
