When you are solving multiplication equations where you are multiplying by 4, you can use the same strategies that you use when you are multiplying by 2. You're just going to do it two times. So, you can double the other number in the equation two times to get whatever your answer is. So, to look at this, we're going to look at the equation 3 x 4. So, we know that we're going to have to double the other number other than four two times. So, we're going to think about doubling three. So, what's 3 + 3? It's 6, and we know we have to do this two times. So, we're going to have 6 + 6 which equals 12. So that means that 3 x 4 = 12 because if you double three two times and add them together, then that equals 12.
