A (very) short history of Covid-19 in 19 characters.
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.

Singapore Math Envy

The desire and hope among a number of developing countries that their own students could do well in math, if they were to adopt a math curriculum similar to the one used in Singapore.
A few local publishers are laughing all the way to the bank, as the result of the Singapore math envy of some African countries, which have started importing Singapore math books for their schools.

Mask Wave

When people from high-risk countries that have been hit by more than one wave of Covid-19 are so paranoid or petrified that they would wear more than one face mask each time—for instance, two masks for a second wave, and three for a third wave.
As Covid-19 second wave hits Singapore, third wave sweeps Delhi, and fourth wave grips Hong Kong, first-world countries are worried that their local supply of masks might be hijacked by a mask wave, as some extreme citizens take extra-precautionary measures to avoid getting infected.

Mathematical Virgin

One who has never experienced the joy (or pain) of rigorous proofs in high-school Euclidean geometry or college calculus.
Angel couldn't understand why mathematicians make such a big fuss about rigorously proving mathematical results that are intuitively obvious to her—one should forgive her for her immaturity as she's still a mathematical virgin.

🇸🇬 🔢

Short for Singapore Math. A mélange of the best math curriculums from the East and the West, which has arguably led Singapore students to repeatedly rank top in international comparative studies like PISA and TIMSS.
In emoji, 🇸🇬 🔢 = (🇺🇸 + 🇬🇧 + 🇨🇳 + 🇰🇷 + 🇷🇺 + 🇮🇱) × 🔢—the six main mathematical ingredients Singapore apparently used to bake its own cake, which is now popular among tens of thousands of math educators and homeschoolers worldwide.

Pi Brexit

When math teachers in a school or state can’t see eye to eye on the degree of accuracy the number π should be given in a math question—for example, should the students be asked to take π to be 22/7 or 3.14?
In the aftermath of the “Pi Brexit” war, a red state in the US has recorded at least a dozen resignations from hardcore evangelical math teachers, who refuse to bulge unless the schools agree to use the biblical value of three for π.

Bar Model Method

A problem-solving visualization heuristic that is the heart of the Singapore math curriculum, whose copyright is being contested by both China and Russia (or even Japan), because they claimed that the “look-see” methodology used to solve challenging word problems in elementary grades originated from them.
In the aftermath of the Singapore’s claim that they and the Canadian songwriter Hugh Harrison own the copyright to the “Count on Me, Singapore” song rather than the Indian composer Joseph Mendoza, China and Russia now want Singapore to compensate them for “plagiarizing” the bar model method for over three decades—unprovenly, it’s their tit-for-tat message to high-GDP Singapore for not approving their home-made, half-baked vaccines.
