Horizontalement :A = (54+19)(43-17)
A = 73 x 26
A = 1898
B = 12 x 13 x 14 - 15
B = 2184 - 15
B = 2169
C = (774x(36+64))/18 + 18
C = (774x100)/18 + 18
C = 4300 + 18
C = 4318
D = (100-(7-4))(103-16)
D = (100-3) x 87
D = 97 x 87
D = 8439
Verticalement :
I = 1987 - 562 - 177
I = 1425 - 177
I = 1248
II = 9 x 9 x 100 + 4 x 10 - 6
II = 8100 + 40 - 6
II = 8140 - 6
II = 8134
III = 3(9x400-2772/7)+1
III = 3(3600 - 396) + 1
III = 3 x 3204 + 1
III = 9612 + 1
III = 9613
IV =81000/(10-1)-100/5+3x3
IV = 81000/9 - 20 + 9
IV = 9000 - 11
IV = 8989
- - I - II - III - IV
A - 1 - 8 - 9 - 8
B - 2 - 1 - 6 - 9
C - 4 - 3 - 1 - 8
D - 8 - 4 - 3 - 9
