Multiplication using the BOX METHOD

Here's how the "box method" works: 23x7  

First you divide the larger number into its separate parts. Here, 23 become 20 and 3.

Next, you multiply each separate part — 20 x 7 and 3 x 7.

Finally, you add all the products together. 140 + 21 equals 161, the product of 23 x 7. 

See how it works!!
