Solve 12-(-2): Understanding Double Negative Subtraction

Question

$12-(-2)=$

00:03 Let's solve this problem.

00:06 Remember, negative times negative always equals positive.

00:11 Now, let's open the parentheses.

00:15 Moving to the right means progress towards the positive side on the number line.

00:20 Let's imagine taking twelve jumps to the right.

00:27 Then, let's take another two jumps to the right.

00:35 And that's how we find the solution to the question!

Let's remember the rule:

$-(-x)=+$

We'll write the exercise in the appropriate form:

$12+(2)=$

We'll locate the number 12 on the number line, from which we'll move 2 steps to the right (since 2 is greater than zero):

We can see that we've reached the number 14.
