Sagot :
A= (-14)+(+16)+(-3)
= 2 + (-3)
= -1
B= (-15)+(-100)+(-7)
= -115 + (-7)
= - 122
= 2 + (-3)
= -1
B= (-15)+(-100)+(-7)
= -115 + (-7)
= - 122
A = -14 + 16 - 3
= -17+16
= -1
B = -15-100-7
= -122
C=4.5-16+3.5
= 8-16
= -8
D=-5+19+48
= -5+67
= 62
E=-5+34+17
= -5+51
= 46
F=3.5+3.4+7-15
= 13.9-15
= -1.1
G=-2+1-5+4+77
= 82-7
= 75
H=-15-4.5+7.5+0.5-1.5
= -21+8
= -13
Voilà j'espère que c'est assez clair ;)
Bon WE :)
