Bonjour

5+3x(-5) = 5 - 15 = - 10

8-(-15+10)x2 = 8 - (- 5) x 2 = 8 - (- 10) = 8 + 10 = 18

-2x8+4x10+2 = - 16 + 40 + 2 = - 16 + 42 = 26

-8+2x(-5)+9 = - 8 + 10 + 9 = - 8 + 19 = 11

(7-9)x(-4-3) = - 2 x (- 7) = 14

-5-10:[3-(-2)] = - 5 - 10 : (3 + 2) = - 5 - 10 : 5 = - 5 - 2 = - 7.

4x[-15-3x(-4)] = 4 x (- 15 + 12) = 4 x - 3 = - 12

1+2-(-3+5)x2 = 1 + 2 - 2 x 2 = 1 + 2 - 4 = 3 - 4 = - 1.
