Question

Can someone help me with this?​

Answer 1

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.

1)

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)

$2+(-6)=-4$

3)

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

4)

$(-7)+3=-4$

5)

$9+(-4)=5$

6)

$-1+4=3$

7)

$5+(-5)=0$

8)

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