It is associated with basic/rough figures traditionally done on the back of a beer coaster at a pub while drinking.
An example might be mates working out the cost of a fishing trip, so "Fuel will be about $100, bait about $50, accom about $200 and good about $200". So rough/approximate figures.

According to my beer coaster maths, it would be about $500. But if you want a more accurate number I'd obviously have to look it up, speak to the suppliers etc.

Short for “Department of Government Efficiency” Math. When a gang of smart alecks directed by some billionaire jerk-nerd come into the workplace and start accessing the personal data of allegedly underperforming or malingering math educators, or heartlessly email them over the weekend about their terminations, particularly targeting those who had unprovenly criticized the radical ideology of the MAGA cult or the conspiracies perpetrated by alt-right groups.
Guesstimate the number of firings that have so far taken place nationwide in the aftermath of the apparently vindictive DOGE math initiative.

Get the DOGE Mathmug. A waste of time. You learn derivatives, but it is unnecessary unless you want to be an engineer. Don't take this course if you love your free time.
