E (mathematical constant)
Imagine you have a pizza that is cut into many, many thin slices. Let's say there are 100 slices. Now imagine that you start adding up the area of each slice, but instead of measuring each slice in inches or centimeters, you measure each slice in a special way. You measure each slice by taking the length of the crust and dividing it by the diameter of the slice.
As you add up the area of each slice using this special measurement, you'll notice that the number you get gets bigger and bigger. But no matter how many slices you add up, you'll never end up with a final number that is exact - there will always be a little bit left over that you can't count. This never-ending number is called "e," and it's a special mathematical constant that appears all throughout the world of math and science. It's used in things like calculating compound interest, understanding the movement of fluids, and even predicting the behavior of subatomic particles. So even though it might seem like just a weird and never-ending number, it's actually really important for understanding how the world works!
