1. Réponse lealebeau40
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
