# What is “To” in Math Terms?

Have you ever heard the phrase “from here to there”? In math, “to” is used in a similar way to show a range or a direction between two points. It helps us understand how far something is or how much something changes.

Here’s how it works:

1. Number Line: Imagine a number line, like a ruler. If you start at number 3 and go to number 7, you can see the distance between those two numbers. You moved from 3 to 7.
2. Range: “To” can also show a range of numbers. For example, if you have 5 to 10 apples, it means you have somewhere between 5 and 10 apples.
3. Equations: In math problems, “to” can show a relationship or direction. If you want to add 2 to 5, you get 7. So, 2 to 5 means you are moving from 2 up to 5.
4. Inequalities: “To” is often used in inequalities to show limits. For example, if you can have between 3 to 8 cookies, you can write it as 3≤x≤83 \leq x \leq 83≤x≤8, where xxx is the number of cookies.

Using “to” helps us understand changes, distances, and limits in math. It’s like giving directions or showing how much something can be.
