Bonjour,
K = 17 x 102
K = 17 x 100 = 1 700
K = 17 x 2 = 34
K = 1700 + 34 = 1 734
L = 86 x 10 = 860
L = 86 x 3 = 258
L = 860 + 258 = 800 + 200 = 1 000
L = 60 + 58 = 118 + 1 000 = 1 118
L = 14 x 10 = 140
L = 14 x 3 = 14 x 3 = 42 (tu rajoute le zéro)
L = 140 + 42 = 182
L = 1 118 + 182 = 1 100 + 182 = 1 282
L = 1 282 + 18 = 1282 + 18 = 1 300
M = 998 x 11
M = 998 x 10 = 9 980 + 980 = 900 + 900 = 1 800
M = 9 980
M= 9 000 + 1 800 = 10 800
M = 98 + 80 = 178
M = 10 800 + 178 = 10 978
