Math for kids | Addition | Adding on an open numberline | Number line

Number lines are the easiest for adding. An open numberine does not have number on it. That's why it's called an open number line.

So how does it work?

You write the first number at the left corner of the line and hop in 1s, 10s or 100s depending on the sum.
