LESSON 2<br />

Addition<br />

Let’s begin by looking at the + (plus) sign.<br />

This symbol means to add. If you see 4 + 5, you<br />

should add four <strong>and</strong> five. Four books plus five<br />

books adds to nine books.<br />

is<br />

I will not try to teach you to add in this<br />

course. This lesson is about symbols. In the next<br />

level, I will show you how to add using a<br />

calculator. For now, I want you to know the<br />

symbol used to show addition. When we read<br />

4+5, we say 4 plus 5.<br />
