Bonsoir,
A = 35 - [4 x (5+2) - 7]
= 35 -(4*10 -7)
= 35 -(40-7)
= 35 - 33 = -2
B = 12 x [32 - (4 + 7) x 2]
=12 *(32 - 11*2)
=12 * (32 - 22)
= 12 * 10 = 120
c = (1+7) x [11 - (2+3) ]
= 8*(11- 5)
=8* 6 48

Bonjour ça va ?
A=35-[4×7-7]
= 35-[28-7]
= 35-28+7
a= 14
B= 12×[32-11×2]
= 12×[32-22]
= 12×10
b =120
c=8×[11-5]
= 8× 6
c=48
