-7+(-4)=.....+(-7) -65+26+65= 67+45+(-67)+55= 25+(-70)+15+70= (-35)+(-60)+35+75+60 Please help ..... kasih contoh nya juga ya

-7+(-4)= (-4) +(-7) = -11

-65+26+65= 65-65+26 = 26

67+45+(-67)+55= 67-67+45+55 = 100

25+(-70)+15+70= 25+15-70+70 = 25+15 = 40

(-35)+(-60)+35+75+60 = -35+35-60+60+75 = 75

1. -7+(-4) = -4+(-7)
2.-65+26+65 = -39+65
= 26
3. 67+45+(-67)+55 = 112+(-67)+55
= 45+55
= 100
4.25+(-70)+15+70 = (-45)+15+70
= 100
5.(-35)+(-60)+35+75+60 = (-25)+35+75+60= 145

-Maaf ya kalo salah (>_<')
