Answer 1

Răspuns:

1.

a-b= -6-(-9)= -6+9= 3

b-a= -9-(-6)= -9+6= -3

|a|-|b|= |-6|-|-9|= 6-9= -3

|b|-|a|= |-9|-|-6|= 9-6= 3

2.

a-b= 12-19= -7

b-a= 19-12= 7

|a|-|b|= |12|-|19|= 12-19= -7

|b|-|a|= |19|-|12|= 19-12= 7

3.

a-b= -10-(+4)= -10-4= -14

b-a= 4-(-10)= 4+10= 14

|a|-|b|= |-10|-|4|= 10-4= 6

|b|-|a|= |4|-|-10|= 4-10= -6

4.

a-b= 5-(-11)= 5+11= 16

b-a= -11-5= -16

|a|-|b|= |5|-|-11|= 5-11= -6

|b|-|a|= |-11|-|5|= 11-5= 6
