1. Réponse yeahmaiko
Réponse:
A = 6
B = -2
Explication :
A = 5-4- (-4+2-3)
= 1 + 4 - 2 + 3 = 5 - 2 + 3 = 6
B = -14+7- (10-29) + (47-61)
= -7 - 10 + 29 + 47 - 61
= -2

A = 5-4-(-4+2 + (-3))
=1+4-2+3
=5-2+3
=3+3
=6
B = -14 + 7 - (10 - 29) + (47 - 61)
=-7-10+29+47-61
=-17+29+47-61
=12+47-61
=59-61
=-2
