When you’re multiplying any number times 2, an easy way you can think about solving these equations is to think about doubling whatever the first number is. So, if you have the equation 4 x 2, you can just think about doubling the 4 or you can think of 4 + 4 which is 8. So, let's look at a visual of this equation to see if we got the right answer. So, in 4 x 2, the first number is 4. So, we're going to have 4 groups with 2 items in each group because 2 is the second number. So, if you count all of the items in these groups, you do have 8 so 4 x 2 = 8. This could work with any equation that you are trying to solve where you're multiplying by 2. So, if you had 100 x 2, you could just add 100 + 100 which equals 200.
