Question

Add the following integers, using number line:

$(-1)+(-2)+(-4)$.

Answer 1

Given: $(-1)+(-2)+(-4)$.

In order to add $-1$ and $-2$, first we move $1$ step to the left of $0$.

Now we move $2$ steps to the left of $-1$ to get $-3$.

Again, we move $4$ steps to the left of $-3$ to get $-7$.

Thus,$(-1)+(-2)+(-4)$$=-7$.
