Bonjour
lorsque a = 3/2 b= -3/2 c =4/-7 calculer en détaillant toute les étapes a égal
a=(a-b)*c
A = (3/2 - (-3/2)) x (4/-7)
A = (3/2 + 3/2) x (-4/7)
A = 6/2 x (-4/7)
A = 3 x (-4/7)
A = -12/7
b= a*b*c.
B = 3/2 x (-3/2) x (-4/7)
B = 9/4 x 4/7
B = 9/7 x 4/4
B = 9/7
c =-a-b+c
C = -3/2 - (-3/2) - 4/7
C = -3/2 + 3/2 - 4/7
C = -4/7
