1.
14+(-7)+(-14)+7+9 = 7-14+16 = 9
2.
(-44)+9-71)+44+71+(-11) = -44+9-71+44+71-11=9-11 = -2
3.
(-35)+25+(-24)+10+24+35 = -10-24+69 = -34+69 = 35
4.
-8+(-22)+30+18+(-17) = -30+30+1 = 1
5.
(-49)+(-1)+(-64)+54+10 = -49-1-64+64 = -50
6.
89+(-27)+81+24+3+(-89) = 89-89-27+27+81 =81
a) 14+(-7)+(-14)+7+9=14-7-14+7+9 = 9
b) (-44)+9-71+44+71+(-11)=-44+9-71+44+71-11=9-11=-2
c) (-35)+25+(-24)+10+24+35=-35+25-24+10+24+35=25+10=35
d) -8+(-22)+30+18+(-17)=-8-22+30+18-17=1
e) (-49)+(-1)+(-64)+54+10 = -49-1-64+54+10 = -50
f)89+(-27)+81+24+3+(-89) = 89-89-27+27+81 =81
