Bonjour,
Verticalement
1) 21,3 x 31 - 17,3 + 1929
= 660,3 - 17,3 + 1929
= 2572
4) 210 : 7 : 5 x (1000 - 9)
= 30 : 5 x (991)
= 6 x 991
= 5946
Horizontalement
a) 5 x (5 + 36 x 11)
= 5 x (5 + 396)
= 5 x 401
= 2005
c) (14521 - 13202) x (48 : 12 x 3 - 6)
= 1319 x (4 x 3 - 6)
= 1319 x (12 - 6)
= 1319 x 6
= 7914
d) 11 x (11 - 4) x (11 + 2) x (11 - 9) + 4
= 11 x 7 x 13 x 2 + 4
= 77 x 26 + 4
= 2002 + 4
= 2006

1). 21,3×31-17,3+1929=660.3-17,3+1929=643+1929=2572
4) 210÷7÷5×(1000-9)=30÷5×991=6×991=5946
a) 5×(5+36×11)=5×(5+396)=5×401=2005
c) (14521-13202)×(48÷12×3-6)=1319×(4×3-6)=1319×(12-6)=1319×6=7914
d) 11×(11-4)×(11+2)×(11-9)+4=11×7×13×2+4=2002+4=2006
