Back-of-the-Mask Thinking
When the crisp-and-crude method of calculation, which yields an approximate instead of an exact answer to a problem, is done on a mask rather than on an envelope or a napkin.
With billions of people wearing a face mask to shield themselves against the coronavirus, the back-of-the-mask thinking is a lifelong guesstimation skill math teachers and tutors worldwide ought to promote to students during this pandemic crisis.

Trumpian Geometry
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.

Trumpezium
An obese- or obscene-looking quadrilateral with zero parallel sides—also known as “trumpezoid” in the Commonwealth countries.

🇨🇳: (🦇 🦠 🧪 🧫 🔬) ➡️ 🌍: (😷x + 💀y)
Eric plagiarized “🇨🇳: (🦇 🦠 🧪 🧫 🔬) ➡️ 🌍: (😷x + 💀y)” from Urban Dictionary and SMSed it to his father, who had nicknamed the coronavirus “China virus,” “Chinese virus,” or “kung flu” in racially charged tweets.

🇸🇦₉₁₁ & 🇨🇳🦠₁₉
Two deadly mass events—the September 11, 2001 terrorist attacks by radical Islamists from Saudi Arabia and the December 2009 coronavirus pandemic spread by Chinese Communists from Wuhan—that had killed thousands of innocent lives due to radical ideology and viral cover-up, with fear, death, loss, pain, and trauma among the common denominators.
Between 🇸🇦₉₁₁ & 🇨🇳🦠₁₉, which event has greater eternal consequences for mankind, besides their present religious and political ramifications on earth?

Covid-🎢
When amusement park visitors who wish to ride a roller coaster are banned from screaming during the minutes-long trip lest their high-pitched voices might spread the virus to those around them if they happen to be asymptomatic.
Political Pi
When the digits of the decimal number π can be used to divine the ups and downs of a politician’s career—apparently a numerological activity by nontenured mathematicians who moonlight for politicians who have faith in the spiritual or occultic power of numbers.
That President Trump’s re-election or rejection by the electorate could be determined by political pi proves that the intersection between pi and politics is not zero.
