Bonjour

(- 12 + 32) x - 2 - 6 = 20 x  - 2 - 6 = - 40 - 6 = - 42

30/6 = 5

1/8 + 3/2 - 15/8 + 1/4

= 1/8 + (3 x 4) / (2 x 4) - 15/8 + (1 x 2) / (4 x 2)

= 1/8 + 12/8 - 15/8 + 2/8

= 15/8 - 15/8

= 0

8/3 x 9/2 = 72/6 = (6 x 12) / (6 x 1) = 12.

6 (x + 5) = 6 (1/3 + 5) = 6 [1/3 + (5 x 3) / (1 x 3)] = 6 (1/3 + 15/3 = 6 * 16/3 = 96/3 = 32.

1/6 + 3/5 = (1 x 5) / (6 x 5) + (3 x 6) / (5 x 6) = 5/30 + 18/30 = 23/30.
