To master the lattice algorithm.
This packet is intended to be an introduction to the lattice multiplication algorithm. This algorithm is sometimes taught in elementary schools, but many adults are unfamiliar with it.
The lattice algorithm is used for multiplying multi-digit numbers. Some important features of the algorithm include:
In this packet, I will solve two problems:
This video demonstrates the lattice algorithm with two two-digit numbers.
This video demonstrates the lattice algorithm with larger numbers.
So you spend a lot of time setting up the lattice, right? It must take a lot longer than the standard algorithm, right?
I'll multiply two 10-digit numbers. Which will be completed first? And by how much?
(Note: While the video is sped up, it still takes two minutes...feel free to fast forward to the end!)
