Bonjour,
A= 6 x 4 + 2 x 7
=24 +14 = 38
E= (3,5+6,5) x (14- 9,5)
= 10* 4,5 =45
I= 10 /( 3 + 7 )
=10/10 = 1
B=6 x (3+7)
=6* 10 = 60
F= [ 5x4 -(1+2)] x 2
=(20 -3)*2
= 17*2 = 34
J= 15 x 2 - 9 / 3
= 30 -3 = 27
C= (130-102) / (0,4x10)
=28 /4= 7
G= 5-[4-(2+1)]
= 5- 1 = 4
K= (0,01 x 124) / (10-3x2)
= 0,0000080645/4
=0,000020161
D= 25 - 8 + 3
= 17+3 = 20
H=14 / 2 x (21 / 3)
= 7 *7 = 49
M= 10 - 9,9 / 3
= 10 - 3,3 =6,7
