We always thought basic math principles were useful, but who knew they could be funny too?
Math is a valuable subject that students are required to learn and practice from the moment they enter kindergarten. Unfortunately, it usually ends up being one of the most hated subjects because the principles and concepts can sometimes be a little hard to understand. For example, one rule we all learned in math is that a negative number multiplied by another negative number is always positive. Okay…but why? A Japanese comic takes aim at that question and uses a real life example to illuminate this little math conundrum.

So basically, the negative of someone you hate coupled with the negative of being hurt equals something positive! That is really easy to understand and makes us feel a little terrible inside, but at least we got the math concept down.
