Question

If you add -6 to 7 and then subtract -8 from the result, what will be the answer? [2 Marks]

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

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

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., $1-(-8)=1+8=9$ [1 Mark]
