Elias omega coding

Elias Omega coding is a way of telling someone how many things there are in a list without using too many letters or numbers.

Think of it like having a box of toys. Instead of saying how many toys are in the box, you could use a secret code to tell someone.

First, you write down the number of toys you want to tell someone about. Let's say there are 10 toys in the box.

Then, you write down how many digits are in that number. The number 10 has 2 digits, so you write down the number 2.

Next, you write down a bunch of 0's. The number of 0's you write down is the same as the number you wrote before (in this case, 2). So, you would write down 00.

Finally, you write down the original number again, but you get rid of the first digit. So, you would write down just the number 0.

So, the secret code for telling someone there are 10 toys in the box using Elias Omega coding would be 20010.

This code doesn't take up as much space as actually writing out all the digits in the number. Plus, it's a fun secret code to use when talking about how many toys you have!
