Let us start by looking at subtraction. Subtraction as you can […]

Lesson 10: Constructing Math Equations with Parentheses

In the last couple of lessons, we have been going over different operator symbols to use for making our desired math equation.  These operators have been: Addition + Subtraction – Multiplication * Division / However, what if we want to have more complex equations?  Just like in algebra, we are going to be using parenthesis!  […]
