Sagot :
bonjour
a. - 4 * - 2 = 8
b. - 5 * - 4 = 20
c. - ( - 6 ) + 4 = 6 + 4 = 10
d. 5 - ( - 5 ) = 5 + 5 = 10
e . 2 * - 12 = - 24
f. 5 - 2 * 2 = 5 - 4 = 1

Bonjour
Explications étape par étape :
a. (9 -13) (-2) = -18 + 26
b. (7-12) X (-8+4) =(-5) X (-4) = +20
c. -(2 - 2x4) + 4 = - ( 2 -8) + 4 = + 6 + 4 = 10
d. 5-(- 2-3) = 5 - ( -5) = 5 + 5 = 10
e. (-3+5) X (-5 - 7) = 2 X -12 = - 24
f. 5 - 2x(-3+5) = 5 - 2 X ( +2) = 5 -4 = 1
