What are notations?

Notations are like secret codes that help us write down big ideas and numbers in a way that makes them easier to understand.

Imagine you're playing with blocks. Each block is a number, and if you stack them up, it shows how many blocks you have altogether. That’s like notation, it helps you see the whole picture without counting every single block one by one.

Think of notations as shortcuts in a game. Instead of saying “I have 10 blocks,” you could just write 10 on a piece of paper. That’s much faster! Or if you’re stacking blocks to show numbers, like building a tower with 2 blocks and then another tower with 3 blocks next to it, notation helps you write that as 2 + 3, which means “two plus three.”

Notations are everywhere. When you write down your age, or count the number of toys in a box, you're using notations, like when you write 5 instead of saying “five.” It's just a fun and faster way to talk about numbers and ideas!
