Vous pouvez m’aider svp en m’indiquant les formule si possible
Calculer
A = (+50,4) + (-17)
C = (-50) + (-17)
B = (-50,4)-(-17)
D = (+50,4) + (+17)

Answer 1

bonjour

A = (+50,4) + (-17) = 50.4 - 17 = 33.4

C = (-50) + (-17) = - 50 - 17 = - 67

B = (-50,4)-(-17) = - 50.4 + 17 = - 33 .4

D = (+50,4) + (+17) = 50.4 + 17 = 67.4
