Bonjour
A1 = 5,5
B1 = 4 x A1 + 12
B1 = 4 x 5,5 + 12
B1 = 22 + 12
B1 = 34
A1 = 34
B1 = (23 + A1)/100
B1 = (23 + 34)/100
B1 = 57/100
B1 = 0,57
A1 = 64
B1 = 2,5 + A1/100
B1 = 2,5 + 64/100
B1 = 250/100 + 64/100
B1 = 89/100
B1 = 0,89
A1 = 25
B1 = 10x(3 x A1 - 5)
B1 = 10(3 x 25 - 5)
B1 = 10(75 - 5)
B1 = 10
A1 = 10
B1 = 3 x A1 x (5 + 2 x A1)
B1 = 3 x 10(5 + 2 x 10)
B1 = 30(5 + 20)
B1 = 30 x 25
B1 = 750
A1 = 10
B1 = A1^3 - 7 x A1^2 (^ : puissance)
B1 = 10^3 - 7 x 10^2
B1 = 1000 - 7 x 100
B1 = 1000 - 700
B1 = 300
