Who invented the numbers we use today and why are they like that?

The numbers we use every day were invented by people who wanted to make counting easier and more fun.

Long ago, people used sticks, pebbles, or even drawings to count things like animals or food. But as cities grew bigger and trade became common, they needed a better way to write down numbers so they could keep track of money, time, and everything else.

That's when Indian mathematicians came up with the idea of digits, those special symbols we use today like 0, 1, 2, all the way to 9. These digits are like building blocks that can be used to make any number you want. Think of them like letters in a word, just as you need letters to spell "cat," you need digits to write "135" or "78."

This system is called the decimal system, and it's so clever because each digit has a place value, kind of like how each letter in a word has its own position and meaning. That’s why 23 means twenty-three, the “2” stands for two tens, and the “3” stands for three ones.

Imagine you have blocks that can stack up to make towers. Each block represents a number, and depending on where it is in the tower (like units, tens, hundreds), its value changes, just like digits in numbers! This makes counting and doing math much easier than ever before.
