Explications étape par étape
A = -7 x 5 + 18/3 - 10
A = -35 + 6 - 10
A = -39
B= ( 8 - 5 x 4) / (2 x 3 - 4 x 3) priorité à la multiplication.
B= (8 - 20) / (6 - 12)
B = -12 / -6
B = 2
C = 100 / (25 / ( 5 x (-3)))
C = 100 / (25 / (-15))
C= 100 x ((-15) / 25)
C = [ (2 x 5)² x (- 3 x 5) ] / 5² on simplifie
C = ( 4 x (-15))
C = -60
D = - 5 + [ -11 x ( 3 + (-2) ) + 4 ] x 2 + 4 x 7
D = - 5 + [ -11 x ( 7 -2) + 4 ] x 2 + 28
D = - 5 + ( -11 x 5 + 4 ) x 2 + 28
D = 23 + (-55 + 4) x 2
D = 23 + (-51 x 2)
D = 23 - 102
D = -79
E = -12 / (-4) + ( -35) / (6 - (-1))
E = 3 + (-35) / (6+1)
E = 3 - 35 / 7
E = 3 - 5
E = -2
j'espère avoir aidé.
