bonjour
A = 24/36 x 9 /27
A = 8 /4 x 1/9
A = 2 x 1/9
A = 2/9
B = 11/4 : 7/18
B = 11/4 x 18/7
B = 198/28 = 99/ 14
C = ( - 5/6 ) : 1/12
C = - 5/6 * 12
C = - 60/6 = - 10
D = 3 - 4 * 5 - 2 ( - 15 + 3 )
d = 3 - 20 - 2 * - 12
D = 3 - 20 + 24
D = 7
E = - 7 - ( - 6 + 1 ) + ( - 2 - 8 )
E = - 7 - ( - 5 ) + ( - 10 )
E = - 7 + 5 - 10
E = - 12
F = 3 * 2 ⁴ - 3 ²
F= 48 - 9
F = 39
