Dear maths, please grow up and solve your own problems.
Until maths has managed this, it's better dumped in your glass. There it can lead its existence as ice cubes in the form of mathematical signs such as Pi, numbers or operators.* To make mathematical ice cubes yourself, simply use this Mathematical Signs Ice Tray. Made of silicone, all you need besides the tray is water and a freezer!
* It's very likely that upside down swimming maths ice cubes will yield new solutions and approaches ;). Prof. Stephen Hawking swears by them.*
