Bonsoir,

A = 5x7 - 3x 6

= 35 - 18

= 17

B = 8 +33 + 11-7

= 41+ 7

= 48

C= 45 - 35/5+5

=45 -7 +5

= 43

D = 6 +7x7 - 64 / 8

= 6 +49 -8

=  47

Bonsoir :)

Explications étape par étape:

A = 5x7 - 3X6

= 35 - 18

= 17

B = 8 +33 + 11-7

= 41 + 4

= 45

C= 45 - 35:5+5

= 45 - 7 +5

= 38 + 5

= 43

D = 6 +7x7 - 64 : 8

= 6 + 49 - 8

= 55 - 8

= 47
