Bonjour

A = ((3 x 7) + (7 x 8))

A = 3 x 7 + 7 x 8

A = 21 + 56

A = 77

B = (5 + 4) x (5 x 4)

B = 5 + 4 x 5 x 4

B = 5 + 20 x 4

B = 5 + 80

B = 85

C = [4 x (5 x (7 x (8 + 10)))]

C = [4 x (5 x (7 x 18))]

C = [4 x (5 x 126)]

C = 4 x 630

C = 2 520

D = (48 : (24 : 3) + (7 + 5) : 2)

D = (48 : 8) + 2 : 2)

D = 6 + 1

D= 7.
