Question

Find the value if you add -6 to 7 and then subtract -8 from the result. also visualise it on number line.

Answer 1

According to the question, we have to add -6 to 7 and then subtract -8 from the result, which means:
7 + (-6) = +1
$\Rightarrow$ 1 - (-8) = 9.
$\left[1mark\right]$

Let's try to visualise this on a number line:

​​​​​​​$\left[1mark\right]$
Stand on 7 on the number line, then move 6 places to the left in order to add -6 to 7, you will reach 1.

Now, move 8 places to the right to subtract -8 from 1, you will reach 9, i.e., $1-(-8)=1+8=9$
