Calcule chacune des expressions suivantes
A = 6 x 4 = 24
D=6x (3+7) = 6 x 10 = 60
E= 130-102 = 28
0,4x 10 = 4
1=25 -8+3 = 28 - 8 = 20
L= (3,5 + 6,5) x (14-9,5) = 10 x 4,5 = 45
N= (5 x 4 - (1 + 2) x 2 = 20 - 3 x 2 = 20 - 6 = 14
1
O=5 - [4 - (2 + 1)] = 5 - (4 - 3) = 5 - 1 = 4
P = 14 ÷ 2 x (21 ÷ 3) = 7 x 7 = 49

S=15 x 2-9÷3 = 30 - 3 = 27
0,01 x 124 = 1,24
T= 10-3×2 = 10 - 6 = 4
Y= 10-9.9 ÷ 3 = 10 - 3,3 = 6,7.
