Double trouble
Multiplication can be pretty easy, if you’re dealing with single digits, but it can get a bit tricky when you start trying to solve double digit numbers. Here’s an easy way to solve them easily every single time!
Using the vertical and crosswise pattern, we can easily multiply large two-digit numbers like the one pictured below.
First, multiply vertically up the right side. 2 x 4 = 8. So, 8 will be the last digit in our answer.
Next, cross-multiply. 3 x 2 = 6 and 4 x 1 = 4. Now add 6 + 4 to get 10. Carry over the 1 like you normally would, and you are left with 0, which will go in front of the 8 we already have.
So, as of now you should have 08 in you answer line.
Lastly, vertically multiply up the left side. 3 x 1 = 3 and add the carried 1. Place that in the front of our answer line and we get 408.
Simple right? Test this method out with the following equations and fill the answers in.
