Finley showed Jen and I a completely new way of doing multiplication she’d been taught by her math teacher last night, and it completely blew my mind. It’s called lattice multiplication, and it uses a different way of organizing the two numbers–first multiplying pairs and then adding their results. It took a little time to get my head around it, but I found it a really clever and useful new way to look at math.
