bonjour

A= 10 - [6 - (5 + 4)]

=10-[6-(9)]

=10-(-3)

=10+3

=13

B = -3 x [12 x 2 - (3-2-5)]

=-3x[24-(-4)]

=-3x(28)

=-84

C = (2 x 5 – 2) x 4+ (-2)​

=(8)x(-8)

=-64

INEQUATION

Bonjour,

Calculer:

A= 10 - [6 - (5 + 4)]

A= 10 - (6-9)

A= 10- (-3)

A= 10+3

A= 13

B = -3 x [12 x 2 -- (3-2-5)]

B= -3(24 - (-4))

B= -3(24+4)

B= -3(28)

B= - 84

C = (2 x 5 – 2) x 4+ (-2)

C=( 10-2)(-8)

C= (8)(-8)

C= -64
