Christmaths with Trump

While the world is anxiously waiting what “Christmas (or Cliff-mas!) gift” North Korean dictator Kim Jong Un has reserved for President Trump, with the two rogue leaders now having revived their name-calling game, and as the world witnesses the impeachment trial of the Liar-in-Chief, how can math educators nevertheless use the caustic and divisive political climate in the US to spice their enrichment or recreational math lessons? How can they generate some mathematical positives from the many political and moral negatives?

A few Christmases ago, I wrote Christmaths: A Creative Problem Solving Math Book, which looks at some parallels between the king of public holidays and the queen of sciences. And now thanks to Donald Trump, his narcissistic, racist, and supremacist behaviors and tweets continue to provide thousands of math teachers worldwide fertile fodder to link math to politics.

The Mathematics of Trump

For many of us living outside the US, who are agnostic about the political views of both Democrat and Republican politicians, it’s hard not to poke fun at American [Trump?] politics.

Below are a sample of published entries, which irreverently looks at some parallelisms between Trump and Math.

Meet the Pinocchio-in-Chief

From Trumpworthy Math, I went on to define two units for measuring falsehood: tru and Pinocchio.

Pinocchio

A unit for measuring how far or how much a politician, dictator, or businessperson is lying to an oft-gullible public—named after a marionette with a long nose, the picture of a dishonest person.

Trump’s denial of having sex with an adult entertainer, while his wife was still pregnant, is at least six Pinocchios.

Lies, White Lies, and Statistics

True or False

(a) Politifact: “76 percent of Trump’s statements were false or mostly false.”

(b) Politico: “Trump told a lie every three minutes and fifteen seconds.”

What is a Trump Number?

Below is one of the two published definitions of a “Trump Number,” which had evaded me for some time, because I just couldn’t nail down a description, without too much falsehood or exaggeration.

Based on your knowledge or readings about Donald Trump, how would you define a “Trump Number”?

The “C” Word Among Atheists and Islamists

Two Christmases ago, when President Trump boasted how he restored the spirit of Christmas among those who worship the King of kings, I coined War on Christmas.

War on Christmas

When conservatives and President Trump have had enough of the political correctness by Democrats that people should say “Happy Holidays” and not “Merry Christmas.”

President Trump is hell-bent on winning the war on Christmas, who bragged that under him Americans can now freely and proudly say “Merry Christmas”—they shouldn’t be hijacked by atheists and Islamists in sharing Christmas greetings to others.

And last Christmas, I christened the following:

Trumpmas

The name Donald Trump would have Christened Christmas if he could have his way—after all, every day, the media unfailingly have something un-Christian to write about him, since he miraculously became the US President.

Those working under him long for the day when Trumpmas would turn into Christmas—probably they’ve to wait until they resign or get fired by the president.

The Existence or Nonexistence of Santa Claus

Following the Christmas phone call between the US President and a lucky child last year, I coined the following:

And that presidential “child-unfriendly” phone call prompted me to pose the following Christmaths question:

Santa’s Proof

Santa Claus (🎅): “Children don’t exist.”

Prove or disprove whether Father Santa is correct or not.

Wrapping a Christmas Present à la Trump 🌲🎉🎊🎄

On November 13, 2017, I tweeted the following:

“Nothing” for Christmas

The Gift of Nothing: When you go shopping and could find nothing to buy as a gift for your best friend or loved ones, why not give them the gift of nothing, because nothing is not for sale? Put nothing in a big box and give it to them. #nothing #zero #gift

Last Christmas Eve, I coined Trumpgifting:

Immoral Math: Quid-Pro-Quo Math, Barr Math, and Mueller Math

With some exaggeration and irreverence, it’s not too difficult to coin some mathematical words or phrases based on how President Trump and his oft-ethically challenged administration misrule the country.

Green Math: Trump’s Climate Hoax

With Donald Trump dumping the Paris Agreement for his personal political agenda, math and science teachers could play their part in educating students about the long-term consequences of the president’s selfish unscientific decision.

Fake Father Christmas

On April 13, 2019, I tweeted the following:

Fake Christmas: What are the odds that President Trump’s hypothesis that global climate change is a hoax could speed up the first Christmas summer in the US or EU? Or when fake Xmas trees permeate the homes? #Christmas #Christmaths #weather #climate #Singapore #math #humor 🌲🔢

The Sharpie Pen and Christmas Cards 🎅 🎄 ✉️

Guesstimate how many Christmas cards (and their envelopes) you can use with a Sharpie pen.

Estimate how long a line you can draw with a Sharpie pen.

If each person sent an average of 30 Christmas cards, how long would the Sharpie pen last them? Three years?

Trump’s Greetings Cards

Last December, to resurrect the lost art of sending Christmas or greetings cards, I coined the following slogan:

Make America Greet Again

Bringing back printed greeting cards as in the good old days before the advent of e-cards —when sending personalized cards meant so much to both senders and receivers.

This festive season, Trump supporters want their president to pass an executive order to ban those working in the US government to send e-cards, as this virtual way of greetings is “robotic” and “dehumanizing”—they want to make America greet again.

by MathPlus December 02, 2018

Guesstimate how many millions of greetings cards would be sent every year in the United States if President Trump were to pass his executive order on banning Christmas e-cards.

BC & AD: Restoring Year Zero

Discuss the social, economic, and political implications if the world were to switch to a “Trumpian calendar.”

Pi Exposition

One way for math educators to poke fun at the disturbingly obscene number of ethically challenged senators in exposing their moral hypocrisy to condone or defend the wrongs of a morally bankrupt president is through the irrational and transcendental number pi.

Or, even evangelical Trump supporters voters who refused to acknowledge or right his moral and political wrongs shouldn’t be let off the hook for condoning or exonerating the sins of a “statistical president.”

Prove that the biblical value of pi, as mentioned in 1 Kings 7:23 and 2 Chronicles 4:2, is 3.

The Aftermath of Christmas

Estimate how many people each year suffer food poisoning after eating Christmas leftovers. About half a million?

Roughly how many unhappy people return their unwanted Christmas presents on Boxing Day (and come home with discounted items)?

A Christmas Gift for Trump

Let me end with two Trump-friendly entries I submitted two months ago:

Blessed Christmas (and Merry Christmaths)!

Life of Pi and Pi of Life

For the majority of us who aren’t born or blessed with a mathematical or symbol-minded brain, but nevertheless appreciate the austere beauty of mathematics, writing about mathematics and math education is the second best thing we’d do to console ourselves that we needn’t be first-rate mathematicians to enjoy the language of science and technology, or to appreciate the science of patterns.

Some mathematicians write novels under a pseudonym to avoid any suspicion from their faculty bosses; others compose limericks and haikus as a creative outlet to showcase their hidden poetic talents. And for the rest of us who are neither novelists nor poets, maybe submitting some definitions to Urban Dictionary, by coining new mathematical words, or redefining old ones, could be the first step to activating that atrophied right part of our brain, which is allegedly responsible for creativity.

On this Pi Day, let me share with fellow math educators eleven approved definitions related to the irrational and transcendental pi. Don’t ask me how many times I got rejected and needed to resubmit some of these definitions again, before the Urban Dictionary editors decided to approve them.

Pre-Pi Day

Pre-Pi Day seems to have been serially downvoted and subsequently deleted to prevent digital abuse, because the approved entry can no longer be accessed.

Be Rejection Proof

Rejection isn’t failure. We keep refining or redefining any rejected definitions until the editors have zero excuses to reject the resubmitted entries. I wished I’d share some recipe for these approved pi definitions, but any attempt to offer some tips to increase a math educator’s chances of getting these math words or terms approved would probably be futile, to say the least.

Over time, although I’ve managed to reduce the odds of rejection, however, some submissions inevitably end up in the little red book of the mean editors—maybe these word doctors had a bad day, or simply because I was submitting some “mathematical crap” that caused me to receive emails like the following:

Urban Dictionary – Pi-rated was not published

Thanks for your definition of Pi-rated!

A few volunteer editors read your definition and decided to not publish it. Don’t take it personally!

Pi-rated
The term to describe any faux facts about the irrational number pi.

On Pi Day, our teacher tricked us with some pi-rated math:
pi is a rational number (22/7);
pi has a different value on the moon that on earth;
pi has a value of three in the Bible.

It’s never too late to be mathematically playful, by playing your part in submitting some irreverent mathematical definitions to enliven your math lessons.

A blessed Pi Day to everyone.
