This week instead of using expanded form to multiply a 3-digit number, we are going to use an ALGORITHM.
So if we wanted to multiply 114 x 4 we are going to use the same symbols to regroup just like adding.
Here are few video links that explain the algorithm. Instead of using the word regroup, the gentleman in the video says "carry" which means the same thing.
