You already know how to add 3 + 4 and so on. But there are many ways to add integers. One way to add integers is by using a number line.

Example

$$ -4+(-3)=\, ?$$



We always start at zero. Our first number is negative four (-4) so we move 4 units to the left. We then have plus negative three (-3) which is the same as subtracting 3 so we move 3 more units to the left. This gives us the value of negative seven, (-7).

$$-4+(-3)=\, ?$$

$$-4-3=-7$$

We do the same thing if we have a positive integer, but instead we move to the right.

$$-4+3=\, ?$$

$$-4+3=-1$$



You can also add integers and variables.

Example

$$13x+(-2)x=\, ?$$

$$13x-2x=$$

$$(13-2)x=11x$$
