The Tetris Box Tee on Life:Curated‘s website doesn't have anything to do with math, but with a little creative wording in the description, the shirt fits with this season's "girls are really, really, dumb" trend. The blurb reads:

Just because you failed 11th grade math class doesn't mean you can't bring some geometry into your life with this Tetris print blouse.

Of course, wearing a cute shirt is the only appropriate way for a woman to bring more geometry into her life. Don't like, crack open a book and try to rectify your long-standing issues with basic math.
