Question

B = (+5)-(-4)
B = (... 5) + (... 4)
B = ??

C = (-26) - (+2)
C = ??
C = ??

D = (-2) - (+5) - (-4)
D = ??
D = ??

Answer 1

Bonjour à toi aussi !!

B = (+5)-(-4)

B = (+ 5) + (+ 4)

B = 9

C = (-26) - (+2)

C = (- 26) + (- 2)

C = - 28

D = (-2) - (+5) - (-4)

D = (- 2) + (- 5) + (+ 4)

D = - 3.
