Solve (-8)+(+12): Adding Integers with Different Signs

Question

Solve the following equation:

$(-8)+(+12)=\text{ ?}$

00:00 Solve

00:04 Find point (-8) on the axis

00:10 Move to the right (positive) direction on the axis

00:15 And this is the solution to the question

First, let's remember the rule:

$+(+x)=+x$

Now let's write the exercise in the following way:

$-8+12=$

We'll draw a number line and place minus 8 on it, then move 12 steps to the right:

Therefore:

$-8+12=4$

$4$
