Trumplation

When you compare a big Tic Tac with a little Tic Tac, which obviously sell at different prices due to their sizes, to define inflation, rather than comparing the prices of two boxes of Tic Tacs of the same size at different times.

MAGAnomics has grossly redefined inflation via trumplation.

Post Truth Math

Also known as “Fake Math,” “Trump Math,” “Bigly Math,” and “BS Math.” Half-lies and conspiracies about or on math and math education, which look superficially or uncritically fun, but they are conceptually dangerous to most semi-innumerates and non-symbol-minded folks.

Millions of MAGA patriots have been brainwashed or radicalized to believe post truth math without questions, which has indirectly led to the banning of some math titles or classics in some puritan circles.

Prime Mates

Prime numbers that produce another prime number when they intimately come together—for example, when primes 2 and 3 have fun together, they produce the prime 23.

Among the first 23 primes, guesstimate what percents of them are potential prime mates.

Does Pi Love Me?

When you are mathematically tickled why you have been experiencing an aha! on or about the number π pretty frequently recently—for no logical or valid reasons, it is as if pi seems to be infatuated with you.

Besides coming up with a few sexy proofs on some pi-related theorems, I spotted my birthdate and my cellphone number 31,415 digits apart among the first ten thousand digits in the decimal number pi. Sounds like a sign from on high that makes me wonder: “Does Pi love me?”

Mathematical Toughies

A term for brain-unfriendly or challenging math questions that generally evoke panic and fear, which may also be accompanied by recurring nightmares, among math-anxious or mathophobic students, parents, and teachers—the opposite of “mathematical slowies.”

For most educated folks, who lack the intelligence or training to solving math contests and olympiad questions, these mathematical toughies are off-putting or repugnant to them.

Working Out Pi

When both professional and amateur mathematicians worldwide go beyond calculating the number π to billions of digits to often set up world records—their effective algorithms or methods or formulas used to achieve these high-precision calculations also directly or indirectly help usher in new developments in mathematics.

The mathematical brethren’s quest for working out pi is like MAGA patriots doing all they can to ensure that their cult leader gets reelected by any means, legal or not.

Bar-Modeling Orthogonality

When incorporating Singapore’s bar model method—the problem-solving visualization strategy to tackle word problems—at the elementary school level and its aim to develop students’ pre-algebraic thinking skills (before they are introduced to formal algebra) are not often partially achievable or necessarily correlated in practice.

Wallet-friendly Singapore math textbooks, workbooks, and teachers’ resources on their own doesn’t guarantee problem-solving mastery—bar-modeling orthogonality seems to be a constant in many traditional American classrooms, often because of teachers’ or parents’ faux perception that a foreign math curriculum or publication is harder (or even inferior) than their local inch-deep-mile-wide one.
