bonjour

a )(-2)×3+(-5)×(-7)+32

A  =  - 6 + 35 + 32

A =  61

B)(-2)×[-6+5×2,4]-17

B =   - 2 x ( - 6 + 12 ) - 17

B = (- 2 x 6 ) - 17

B = - 12 - 17

B = - 29

C  1/3 + 3/4 - 2

C =   4/12 + 9/12 - 24/12

=  - 11 /12

D) (2/3+3/ 5)÷ 8/3

= ( 10/15 + 9/15) ; 8/3

= 19/15 x 3/8

= 57/ 120

=  19/40
