00:04 Let's solve this problem together.
00:08 Remember, a negative times a negative always equals a positive.
00:13 Alright, let's open the parentheses.
00:17 Here, the number is negative.
00:20 On a number line, going left means moving towards the negative side.
00:25 So from zero, we'll make two jumps to the left.
00:30 Now, this number is positive.
00:34 And moving right means we're heading towards the positive side.
00:39 Let's take five jumps to the right.
00:44 And there we have it! That's how we find the solution.

Step-by-step solution

Let's remember the rule:

−(−x)=+ -(-x)=+

We'll write the exercise in the appropriate form:

−2+(5)= -2+(5)=

We'll locate the number minus 2 on the number line, from there we'll move 5 steps to the right (since 5 is greater than zero):

-10-10-10-8-8-8-6-6-6-4-4-4-2-2-2000222

We can see that we've reached the number 3.
