Pizza Day

When crypto investors reminisce that a pizza restaurant accepted 10,000 bitcoins in exchange for two large pizzas on May 22, 2010—the bitcoin was then worth 41 bucks.

Out-of-Order Math

When someone fails to carry out the operations in a math problem correctly, often because they couldn’t remember the rule, or they use their own oft-flawed logic to do so.
John flunked his recent class test, because he’s a victim of out-of-order math—he repeatedly misused the BODMAS rule to simplify arithmetic expressions, and misapplied the procedure to find the inverse of a matrix.

Pitian

A fan or follower of the number π, who is preoccupied with, or passionate about, her numerical and geometric properties—a pi equivalent of a born-again Christian, whose faith in the mathematical constant is as solid as a house built upon a rock.
Guesstimate the population size of pitians worldwide, who long to experience an aha every now and then, just as Spirit-filled believers who witness those suddenlies, breakthroughs, or miracles in their lives and on those whom they’ve prayed for.

Pidemic

Short for “Pi Pandemic.” A frightening 2D or 3D mathematical meme or short clip released by some rogue mathematicians or math educators on the number π to terrorize millions of students and their parents, many of whom suffer from math anxiety to a certain degree.
The pidemic is a great awakening among members of the global mathematical community in the midst of the Covid-19 pandemic, as they’re clueless how to help an oft-math-anxious or semi-innumerate lay public to come to terms with these two evils.

Pi Thinking

A metaphorical way of saying to think creatively or divergently or laterally so that you might increase your chances of experiencing an aha!, just as the number π that beautifully or elegantly reveals itself in unexpected ways that its presence or occurrence often gives the reader a deep sense of mental satisfaction or excitement.
Besides showing thinking, window thinking, and sink thinking, where these activities often trigger an aha!, indulging in pi thinking ought to be encouraged as well.

Pi Your Bitcoin

When crypto scammers promise gullible or get-rich-quick folks that they could help them generate π times the bitcoin they send them within a certain timeframe for a wallet-friendly fee.
Countless sites boldly advertise their “Pi Your Bitcoin” schemes, by putting the word “legit” to make people believe it’s not a scam.

3 = 2 + 1

A numerical relationship or statement that most kindergarteners and elementary school students reject as being an equation, because in their minds the “answer” or the “sum” must always be on the right side of an equation.
When students don’t consider numerical liaisons like 3 = 2 + 1 and 1 = 3 – 2 as valid equations or mathematical sentences, their responses reveal a fair bit about their thinking processes.
