Bonjour

a= 24-3x6+2²-72:(-3)

a = 24 - 18 + 4 + 24

a = 24 + 24 + 4 - 18

a = 34

b= -38+7x3-3²+12:(-2)

b = - 38 + 21 - 6 - 6

b = - 38 - 12 + 21

b = - 50 + 21

b = - 29

c= -(12+3x2)+13-15

c = - (12 + 6) - 2

c = - 12 - 6 - 2

c = - 20

d= (-2)²x(3x7-6):3-3

d = 4 x (21 - 6) : 3 - 3

d = 4 x 15 : 3 - 3

d = 60 : 3 - 3

d = 20 - 3

d = 17

e= -12 : 3-3x2+5

e = - 4 - 6 + 5

e = - 10 + 5

e = - 5

f= 12-8 : (6-5x2)

f = 12 - 8 : (6 - 10)

f = 12 - 8 : (- 4)

f = 12 + 2

f = 14.
