## Elementary Math (K-6th) Tutorial

*Multiply by 2's*

#### Intro

When multiplying any numbers together, it does not matter which order the numbers are multiplied. For example, 2 times 4 can also be solved as 4 times 2. The number will still equal the same thing.

When multiplying by 2’s, you are doubling the number opposite of the 2. When you are multiplying 2 times 2, you are doubling the two. Which means 2 two different times, is four. You can also look at the problem as 2 plus 2 because you are doubling the 2.

If you have the problem 2 times 3, you are going to be doubling the 3. Three two different times is 6 (3+3=6).

This rule applied to any number multiplied by 2.

#### Sample Problem

2 times 4 =

2 times 6 =

2 times 7 =

2 times 10 =

#### Solution

8 (4+4=8)

12 (6+6=12)

14 (7+7+14)

20 (10+10=20)
