I hate math. There are no ifs ands or buts about it. There's nothing worse than sitting in a math class all day listening to a lecture about derivatives, secants, integrals, finding the area under the curve, rotating the figure around a point on the y-axis, blah blah blah! However, there is hope in the world of eternal darkness known as math, for I present to you, Dragon Ball By Number! This is a comprehensive list of all numbers used in the Dragon Ball story. Some facts within this section were unbeknowst to even me before I started looking through the list taken straight from Dragon Ball Daizenshyu 7. This list may not suddenly teach you Calculus 3, but at least you'll have something nice to read during that lecture!
