What are expressions?

An expression is like a recipe that tells you how to make something new using ingredients you already know.

Imagine you're playing with building blocks. Each block is a number or a symbol, and when you put them together in a special way, you create an expression. It's like saying, "I want to combine these numbers and operations to find the answer."

Think of it like adding ingredients to a smoothie. If you have 3 apples and you add 2 more, your expression is 3 + 2. That’s how you tell someone exactly what steps to follow to get the total number of apples.

Or if you're sharing candies with friends and want to know how many each person gets, you might use an expression like 10 ÷ 2, which means "divide 10 candies among 2 people."

Expressions can be simple or complicated, just like a recipe can have a few steps or lots of them. But they always give you a clear way to find the answer, one step at a time.
