Sagot :

A = 72 - 42
A = 30

C = (13-4) x 6 - 3
C = 9 x 6 - 3
C = 54 - 3
C = 51

E = 30 - (8-5) x 2 - 1
E = 30 - 3 x 2 - 1
E = 30 - 6 - 1
E = 30 - 7
E = 23

Réponse:

Normalment je crois que c ça :

A=72-42

=30

C=9×6-3

=54-3

=51

E=30-3×2-1

=30-6×2-1

=30-12-1

=18-1

=17

Mais si c ça tu exagére c hyper simple
