6. (14 - 8) - (29 - 19) =​

Answer 1

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
