Sagot :
Bonjour,
g) 3+2 -6-(-8)+7
= 3+2-6 +8 +7 = 14
h) (-2)-(-3)+(-5)-(+6)+3
= -2+3-5-6 +3= -7
i)-9-(-6)+(-3) -(+2)-(-5)
= -9 +6 -3 -2 -5 = ( je te laisse compter )
k) - 8+3 - 7,5+3 -2,5
= -12
– 29+ 20 – 33 + 29+13
= 0
m) -2-(4-6)-(10-8 )
= -2+4+6-10+8 = (je te laisse compter)
3) 7 - 2 +3 – 4 +12-5
= 11
