Prime numbers are like the building blocks of all other numbers. Imagine you have a special group of numbers that can’t be divided evenly by anything except 1 and themselves, those are prime numbers! For example, 2 is a prime number because it can only be divided by 1 and itself. The same goes for 3, 5, and 7.

Prime numbers are important in math and even used in real life to keep your information safe on the internet!

- A prime number like 2 can only be divided by 1 and itself, no other numbers work!
- 3 is a prime number because it doesn’t divide evenly by any number except 1 and 3.
- 7 is also a prime, just like the days of the week, you can’t split them up evenly!
