Calculer chaque expression.

R:14 -17-(-3)-14+3

= 14 - 17 + 3 - 14 + 3

= 14 - 14 - 17 + 3 + 3

= - 17 + 6

= - 11

S:-2,5+4,8 +3,2-2,7

= - 2,5 - 2,7 + 4,8 + 3,2

= - 5,2 + 8

= 2,8

Q:5-7+14-(-9)+3

= 5 - 7 + 14 + 9 + 3

= - 7 + 5 + 14 + 9 + 3

= - 7 + 31

= 24

Calculer :

D:(-4)+(-3)-5-3+(-2)

= - 4 - 3 - 5 - 3 - 2

= - 17

E:3-12+15-17-23

= - 12 - 17 - 23 + 3 + 15

= - 52 + 18

= - 34.
