A postmodern form of geometry that promotes flawed thinking, where the correctness of a proof is relative—for example, in a geometric figure, if an angle looks right, then it is unquestionably taken to be ninety degrees; or if a line segment appears straight, then there is no reason to doubt otherwise.
Trumpian Geometry seems to exhibit the pattern of assumption-intimidation-conclusion, where answers to geometric problems are countries-dependent—for example, the answers to most questions when solved in Russia, Saudi Arabia, and North Korea are the same, but are situationally different elsewhere.

When the irrational number π appears to be particularly attracted to numerical buddies like e, i, and 𝜙 whenever they are indulged in some extra-mathematical activities together, as revealed by their intimate liaisons.
Don’t the following numerical relationships prove that pi and friends have an affinity for one another?
π ≈ 6/5 𝜙²
π ≈ (9 – e)
iⁱ = e^(-π/2)
e^(iπ) + 1 = 0
(- )! = √π
eⁱˣ = cos x + i sin x
π ≈ 6/5 𝜙²
π ≈ (9 – e)
iⁱ = e^(-π/2)
e^(iπ) + 1 = 0
(- )! = √π
eⁱˣ = cos x + i sin x

Short for “Coronavirus Sudoku.” A sudoku that uses nine corona variants represented by the Greek characters (⍺, β, 𝛾, 𝛿, …) rather than numbers 1–9 to make it look devilishly harder to solve.
MathPlus Publishing is releasing “Coronadoku for Gifted Kids” before the Lunar New Year as a reminder of the initial number of people who died of the coronavirus in Wuhan, before the epidemic became a pandemic.

When the authorities ruthlessly enforce the wearing of masks in public places for both people and pets, and also for the thousands of mute and deaf gods and goddesses (or deities and idols) in religious quarters, to contain the surge of infections and fatalities, so that those who fail to do so are dealt with severely, with heavy fines and jail sentences for anti-maskers, or even caning for repeated offenders.
For rogue nations, mobilizing thousands of ambassadors nationwide in begging the public to don a face mask is a waste of time and a sign of political weakness; what the dictators want is to launch a mask operation to get the whole nation into quick action.

A social disease whereby customers use their cellphones to order their food, by being overdependent on food delivery rather than cooking at home, or walking a few minutes to a nearby coffeeshop, hawker center, or foodcourt.
Guesstimate how many Singaporeans suffering from lazy-roo would develop health or mobility issues every year long before they could afford to retire.

When a racist and xenophobic political leader decries most non-white immigrants who landed in America as a bunch of AIDS carriers, lazy burgers, criminals, rapists, terrorists, or jobs stealers.
President Trump blames disloyal politicians and lawyers, who are defending millions of illegal or undocumented immigrants, because they threaten the lives of hardworking Americans—he wants to make America white again, by making it harder for black and colored peoples to seek a better life in the United States.

When someone’s birthday falls on the most important date of the math calendar—when the most number of pies and pizzas are unprovenly being ordered on a single day by math educators and mathematicians worldwide to celebrate the number π.
What is the probability that a pirthday baby would also be experiencing their last day on earth on Pi Day?
