Can someone help me with this?

Mariulka [41]

Answer:

1) $4+5=9$ .

2) $2+(-6)=-4$

3) $-3+(-7)=-10$

4) $(-7)+3=-4$

5) $9+(-4)=5$

6) $-1+4=3$

7) $5+(-5)=0$

8) $-3+(-6)=-9$

Step-by-step explanation:

In the given number lines, rightarrows represent positive integers and leftarrows represent negative integers.

In first number line we have two rightarrows.

Rightarrow from 0-4 = 4

Rightarrow from 4-9 = 5

So, required sum is $4+5=9$ .

Similarly,

$2+(-6)=-4$

$-3+(-7)=-10$

$(-7)+3=-4$

$9+(-4)=5$

$-1+4=3$

$5+(-5)=0$

$-3+(-6)=-9$
