Lattice Method

I was just working on some multiplication problems I had to do for my class. A couple of my classmates didnt know the easiest way to multiply large numbers. There are multiple ways that I've learned throughout my education but the easiest and my personal favorite is the lattice method. The lattice method makes multipling big numbers extremely easy by only having to do multiplication with numbers 0-9. It uses multiplication of small numbers and simple addition to get your final answer.
Here's what the Lattice Method looks like. You put the numbers you are multiplying in the top and right sides of the box in this example we're multiplying 948 and 827
8*9 = 72
2*9 = 18
7*3 = 63
After you are finished multiplying these numbers add them together throughout the rest of the lines carrying numbers as needed. If you want more information visit this website that more throughly explains how to use the lattice method.
