=-7-6

=-13

c)+(-10)-(-4)=

=-10+4

=-6

d)-(-9)-(+1)=

=+9-1

=+8

e)+(-8+5)-(+11)=

=+(-3)-11

=-3-11

=-14

F)-(+7-10)+(-5)

=-(-3)-5

=+3-5

=-2

g)+(+12-9)-(+10)=

=+(+3)-10

=3-10

=-7

H)-(-17-12)+(-30)=

=-(-29)-30

=+29-30

=-1

2)a)-(+5)+(-4)-(+3)+(+5)-(-9)-(+8)=

=-5-4-4+5+9-8

=-7

b)-2-(+2-7+8)+(-7+3)-(-5)=

=-2-(3)+(-4)+5

=-2-3-4+5

=-4

c)+8-[-6+(-4+2)-8-6]-(+10)=

=+8-[-6+(-2)-8-6]-10

=+8-[-6-2-8-6]-10

=+8-[-22]-10

=+8+22-10

=20

d)-[+5-9-(-1-6+9)-2+3]-7=

= -[+5-9-(2)-2+3]-7

=-[+5-9-2-2+3]-7

=-[-5]-7

=+5-7

= -2

e) +[-12+5-(+8-6)-(-7)+11]=

=+[-12+5-(2)+7+11]

=+[-12+5-2+7+11]

=+[9]

=+9
