a) (99)+(+102)+(+1)+(-2) = 99+102+1-2 = 202-2= 200
b)(-1999) +(+7)+(+1995)-(-0) = 1999+7+1995+0 = 4001
c) (+304)+(-4)+(209)+(-1)+0 = 304-4+209-1+0 = 513-3= 510
d) 2001+(+32)+(-42)+(-32)+(+42)+(-1)= 2001+32-42-32+42-1 = 2075-75= 2000


6.
a) |+5|+|-5|+|-7|+|-3|-|-5|-|-7| = 5+5+7+3+5+7 = 32
b) |3-5|+|3|+|-5| = |-2|+3+5= 2+3+5= 10
c) |9+(-3)|+|+9|-|-3|= |9-3|+9-3= |6| +9-3= 6+9-3= 15-3= 12
d) |-15|+|0|+|+15|-|-0|= 15+0+15-0= 30
