What is a bar graph?

A bar graph is when you put squares into a big square and add numbers to the Horizontal side, known as the sum, and the one that goes up. This only exists in math while learning numbers. It could also be homework, also known as a math worksheet. I did that in 5D in Mathtime. I always have math upstairs in 5D because it's my favorite room in B.H.E.S. Because Math is my favorite subject in school, I love learning numbers a whole lot.
