calculer les expressions suivantes aidez-moi SVP ? ??

bonjour

A = 3 + 4 * 125
A = 3 + 500
a = 503

 B = - 7 - 2 *100
b =  - 7 - 200
b = - 207

c = (4 *9)/2 + 9
c = 18 + 9 = 27

d = 5 * 36 - 144/10
d = 180 - 144/10
d = 1800/10 - 144/10 = 1656/10

e = 72 * 4 + 32/5
e = 288 + 32/5
e = 1440/5 + 32/5 
e = 1742/5
