Calcule chaque expression numérique

a) 3 + 2 * 3 = 3 + 6 = 9
b) 7 * 4 - 2 * 6 = 28 - 12 = 16
c) 9/3 + 3 * 4 = 3 + 12 = 15
d) 6 * 4 - 2/4 = 24 - 0,5 = 23,5
e) (3 + 2) * 3 = 6 x 3 = 18
f) 7 * (4 - 2) * 6 = 7 x (2) x 6 = 14 x 6 = 84
g) 9/(3 + 3) * 4 = 9 : 6 x 4 = 1,5 x 4 = 6
h) 6 * (4 - 2)/4 = 6 x 2 : 4 = 12 : 4 = 3
