Answer 1

Answer:

1.3

2.-6

3.-8

4.5

5.-6

6.2

Answer 2

Step-by-step explanation:

In this question

We need to add the following integers,

a)9+(-6) = on number line +9  is 9 places right to 0 and -6 is 6 places left to 0

Therefore, -9+6 = 3

b)5+(-11) = on number line +5 is 5 paces right to 0 and -11 is 11 places left to 0

Therefore, 5-11 = -6

c)(-1)+(-7) = on number line -1 is 1 places left to 0 and - 7 is 7 places left to 0

Therefore,-1-7 = -8

d)(-5)+10 = on number line  -5 is places left to 0 and +10 is 10 places right to 0.

Therefore,-5+10 = 5

d)(-1)+(-2) = on number line -1 is 1 places left to 0 and -2 is 2 places left to 0

Therefore, -1-1 = -3

e)(-1)+(-2)+(-3) = -1 is 1 places left to 0 , -2 is 2 places left to 0 and -3 3 places left to 3

Therefore -1-2-3 = -4

f)(-2)+8+(-4) = -2 is 2 places left to 0 , 8 is 8 places right to 0 and -4 is 4 places left to 0

Therefore -2+8-4 = 2
