Math

In math today we started chapter 8. The chapter is about Variables and Expressions. for example: n - variable, n+4=9 - equation. Our first thing we did was Solving Equations. That topic is about solving a problem like x-3=5. If you add a number on one side you have to add the same number on the other side. This is how you do it,

x-3=5

x-3+3=5+3

x=8
