Bonjour
Calcule.
K= 5 + 13 - 4 + 3 - 6
K = 5 + 13 + 3 - 4 - 6
K = 21 - 10
K = 11
L = - 7 + 5 - 4 - 8 + 13
L = -7 - 4 - 8 + 5 + 13
L = -19 + 18
L = -1
M = - 8 + 5 – 4 + 3 + 4
M = -8 + 5 + 3 - 4 + 4
M = -8 + 8
M = 0
N = - 17 + 24 – 18 – 18 + 19
N = -17 - 18 - 18 + 24 + 19
N = -53 + 43
N = -10
P = 12 – 17 – 13 + 9 + 7
P = 12 + 9 + 7 - 17 - 13
P = 28 - 30
P = -2
