Math is short for "mad cool" in the 2010 Cartoon Network TV series Adventure Time, this phrase is somewhat commonly used by the people of OOO to express something that's very exciting or awesome.
While this slang has nothing to do with the actual subject of Math it's also believed that Finn originated this slang word, Finn is actually terrible at Math as told to us by Princess Bubblegum in the very first episode "Slumber Party Panic" when Finn was taken into trial by the Gumball Guardians.
Finn also has other Math related slang in his vocabulary such as "Mathematical" and "Algebraic" which are slang fairly commonly used in the show as well.

Something that doesn’t make sense. I.e how the paper towel Companies are always trying sell you less rolls but tell You it’s more rolls. For instance Bounty 6 pack but the package says it’s really 12rolls.
Lance said he was going to send me a screenshot of his cracked screen…clearly he is doing Paper Towel Math because you can’t screenshot the crack on your screen 🤦🏾 ♀️

Get the Paper Towel Mathmug. The incorrect British spelling of “Math,” where they add a plural to the end and try to justify it as a contraction
Steve, I just finished all my maths.
It’s a contraction of mathematics, Steve. Pronounce it correctly like me.
Steve later told him to go eat a dick
