Let’s Celebrate Pi Day!
Out of the infinitely many digits of pi, the first three are usually all you need. By rounding pi to 3.14, you get a “close enough” answer to most everyday math problems. But here’s the good part: since March is the 3rd month of the year, every 14th of March is 3-14, so, we call it Pi Day. Because “pi” sounds like “pie”, we make a little math joke and eat pie, which is an excellent way to celebrate anything.

What Kind of Number Is Pi?
Sometimes it’s fun and interesting to ask what kind of number some number is. That’s certainly true of pi.
Pi is irrational, which means that you can’t get it by adding, subtracting, multiplying, or dividing whole numbers. More commonly, we say “you can’t express it as a fraction.” which means pretty much the same thing.
It’s also transcendental, which takes some explaining to define officially, but basically means that you can’t even make it by taking the roots of numbers. Pi is a real number. Additionally, it’s a complex number (all real numbers are complex numbers.)
Not only you can’t write pi as a fraction, but you can’t write it as a decimal either. That’s because, technically, decimals are a special kind of fraction. But what you can do, writing it as a decimal, is approximate it as close as you would like. When you do that, you can get closer and closer forever, writing digits on and on infinitely without falling into any repetitive pattern.
