Some numbers like to hide. Imagine you are looking for a special kind of number that keeps changing every time you try to pin it down, it’s like trying to catch smoke with your hands! These hidden numbers can’t be written as simple fractions, and they keep on going forever. They're called irrational numbers, and one of the most famous ones is pi, which is used to calculate the size of circles.
Examples
- A hidden number like pi keeps changing forever, it's like trying to measure something with an endless ruler.

√(2)as a fraction, it just won't stop changing, it hides from simple math rules. - Hidden numbers are everywhere in nature and science, but they're tricky to catch with our usual tools.
