LESSON 1: Basic Operations – Neat Notebook

What is a neat notebook anyway? It’s where you get to sit by the fire with a friend and a hot cocoa to discuss and compare a topic in math. This first topic is the Basic Operations, which are addition, subtraction, multiplication, and division. We’re going to look at the standard algorithm for each of those algorithms and see if we notice any patterns. We’ll also see if we know all the important vocabulary words associated with these algorithms!
