Okay kiddo, have you ever seen different symbols and letters in different languages? Like when you see "Hi" in English, it looks different than "Hola" in Spanish? That's because different languages use different symbols and letters to mean the same thing.
Now, let's talk about numbers. Just like letters, different languages use different symbols to represent numbers. For example, in English we use these symbols to represent numbers: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. But in other languages, they might use different symbols that we might not recognize.
Unicode is a system that was created to make sure that every symbol and letter from different languages can be represented and understood by computers. This includes number symbols. Unicode has a special set of symbols just for numbers so that they can be used in any language around the world.
These symbols are called "Unicode numerals". They include numbers from 0 to 9 but also have special symbols for things like fractions, percentages, and even Roman numerals. So, no matter what language you're writing in or what kind of numbers you need to use, Unicode numerals have got you covered!
