Exercice 5 Pour chaque cas, transforme la soustraction en addition puis effectue le calcul.
|A = (-12)-(+15) = (-12) (15)
A = ( ...)
B = (-45)-(-41) = (-45) (41)
B = ( ....)
C = (+32)-(+27) = (+32)... (...)
C = (........ )​

Bonjour !

Merci de penser à la politesse lorsque tu poses une question.

[tex]A = (-12)-(+15)\\A = (-12)+(-15)\\\boxed{A=-27}[/tex]

[tex]B = (-45)-(-41)\ \ \ \ \ \ \ (- \ - = > +)\\B = (-45)+(+41)\\\boxed{B=-4}[/tex]

[tex]C = (+32)-(+27)\\C = (+32)+(-27)\\\boxed{C=5}[/tex]

Bonne journée

bonjour

A = (-12) - (+15) = (-12) + (-15)                            - ( +     =    + ( -

A = ( -27)

B = (-45) - ( -41) = (-45) + (+41)                            - ( -   =    + ( +

B = (-4)

C = (+32) - (+27) = (+32) + (-27)

C = (+ 5)​
