### Theory:

Subtraction on number line:

The subtraction of integer can be represented using the number line figure. Now let's see how it is.

Now we are going to subtract the two number which is $$7$$ and $$5$$ in a number line.

We can find this using the following steps:

1. Start from $$7$$, since $$5$$ is being subtracted, so move $$5$$ jumps towards the left side of the number line with $$1$$ jump of $$1$$ unit.

2. Then we reach the point $$2$$.

Therefore we get $$7 – 5 = 2$$.

Therefore using this method we can do the subtraction in a number line.
