Explications étape par étape:
A = -5 -2 * (20+3*(-6))
A = -5-2*(20-18)
A = -5-2*2
A = -5-4
A = -9
B = 3-(6*(+2)-6*3)*(-2)
B = 3-(12-18)*(-2)
B = 3-(-6)*(-2)
B = 3+6*(-2)
B = 3-12
B = -9
C = (-3+1-9)-(6-11+3)+(-5-11-10)
C = -11 -(-2)+(-26)
C = -11+2-26
C = -35
Bonjour,
A= -5-2( 20 -18)
= -5 -2*2
= -5 -4
= -9
B= 3-( 12 -18) * -2
= 3 -( -6) *2
= 3 -(-12)
=3+12 =15
C=
-11 -( -2 ) - ( 26)
= -11 +2 -26
= -35
