Algebra is already hard enough without this kind of mind-bending trouble thrown into the equation.

This algebra textbook has become an internet sensation. Take a look why (note the NSFW language)

Wow, through what wormhole did those kids escape to wind up posing for a textbook? You'd think that if they traveled through time or another dimension, they'd have more pressing matters than modeling for a book cover. But, you know what? We've never traveled through time or dimensions, so we don't know what item number one of the agenda would be when we were to cross the threshold.

As it turns out, this textbook first appeared online on Reddit two years ago. One of the models even posed with the book, too.

Of course, none of this info has stopped the good people of the internet from reacting to the photo. Our take? Just skip math.
