A handful of numbers have a very special property: you can add their digits together and divide the original number by their total without a remainder. And why does it matter? Well, in terms of mathematics, it's mostly a curiosity. Dattatreya Ramchandra (D. R.) Kaprekar saw these numbers as sparking joy in the mind, so he named them "Harshad" numbers, with harshad being the Sanskrit word for joy. And it's an important lesson about numbers: not every bit of math needs to change the world. Something that makes you go "huh" for a brief moment can be enough.

The Dangerous Math Used To Predict Criminals

$2/3 Doesnt SEEM Like a Big Deal, But It Is #shorts Think about how people discovered fractions and what problem they were meant to solve. How do we take a thing and express its division into smaller equal parts? A lot of little somethings add up to 1... until 2/3 came along. Using a numerator that isnt 1 doesnt sound like much, but it was a massive conceptual leap for humanity. #shorts$

$The 24 Card Math Game #shorts The 24 game that originated in China is a fast-paced 2-player game of number manipulatiin. Your goal is to take the integers of the 4 cards on the table and turn them into the number 24, and any mathematical operation is fair game. Add, subtract, divide, multiply, fractions, exponents, factorials... anything goes, as long as the end result is 24 and your math checks out. The rules are simple: aces are worth 1, face cards are worth 10, and the other numbers are themselves. Each player flips 2 cards and the first to invent a combination yielding 24 puts all 4 cards at the bottom of their stack. Keep going until one player has all the cards, and then PLAY AGAIN. #shorts$
