December 22 is also the birthday of my 3rd son. I’ll have to let him know that it’s also National Mathematics Day in India. He’s a nerd.
Party trick:
Start with any four digits between 1 and 9. Ex 7145
Arrange them in descending order, ex 7541
Arrange them in ascending order. 1457
Subtract. 6084
Repeat with this new number. 8640
Subtract 0468
8172
Repeat until you get a number that puts you in a closed loop. It’ll ALWAYS be 6174, Kaprekar’s Constant. No matter which four digits you start with.
We should not be observing National Mathematics Day. Mathematics is racist. That’s why Oregon passed a law ending math proficiency requirements for students.
I thought the only math they teach in today’s el/hi schools is what method is used to count the actual number of genders and pronouns.
Srinivasa Ramanujan, huh. BLM has labeled math as racist.
The latest is sleep is racist, smh.
