How To Do The Box Method For Multiplication?

Here’s how the “box method” works:
  1. First you divide the larger number into its separate parts. Here, 23 becomes 20 and 3.
  2. Next, you multiply each separate part — 20 x 7 and 3 x 7.
  3. Finally, you add all the products together. 140 + 21 equals 161, the product of 23 x 7.
