In 102, people started using numbers to count things more clearly and do bigger math problems.
Imagine you have a bag of marbles. If you're counting them one by one like "1, 2, 3..." that's simple. But if you want to know how many marbles you have together with your friend, or how many you need for a game, it helps to use numbers and write them down.
In 102, people started using symbols, like the number "1" and "2", to show amounts. This made it easier to add things up, just like when you count how many cookies are on your plate by grouping them into piles of 5 or 10.
It’s a bit like learning how to use labels on your toys so you know which ones belong together. Instead of saying “a lot,” people could say “102 marbles”, and that made everything more clear and fun!
