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 />
