Pi (π) is an extraordinary mathematical constant that has fascinated mathematicians and enthusiasts alike for centuries. It represents the ratio of a circle’s circumference to its diameter and is approximately equal to 3.14159. However, pi is an irrational number, meaning it cannot be expressed as a finite decimal or a fraction. Its decimal representation goes on infinitely without any repeating pattern, making it a challenging number to remember. In this guide, we will explore various techniques and mnemonic devices that can help you remember the digits of pi more easily. Whether you are a student studying mathematics or simply curious about this enigmatic number, these strategies will aid you in your journey of memorizing pi.

Pi is the ratio of the circumference to the diameter (diameter is 2 times the radius) of a circle. Calculating pi is a popular way to measure the computing power of supercomputers, and mathematicians now know that there are approximately 10 trillion digits of pi. The world record holder can read tens of thousands of digits, and neurosurgeon and professor Andriy Slyusarchuk claims to have memorized 30 million digits, which takes 347 days of continuous reading. Impressive!
Steps
Group of Digits
- Start with groups of four digits: (3.141)(5926)(5358)(9793)(2384)(6264)(3383),…
- Start by memorizing four groups of four digits. You can work your way up to ten groups of four numbers, remembering only one more group at a time. Then double it up by memorizing five groups of eight digits. The number of digits will remain the same, but you will be able to improve your memorization by including larger “groups”.
- Name them alphabetically so that after you’ve memorized the first 260 digits you can go back and complete your “contacts.”
- Try using real names and associating actual events with the names on the list, or even making up something about each person. The more closely you associate the numbers with the list of names in your head, the easier it will be to remember the numbers.
- You can also combine this technique with the large system and linking technique given below.
Use Alternative Words and Sounds
- A poem pi: “Now I will rhyme, / In words, guided. / Try to create, / Bounce and remember forever. / Width in the circle, / Appear in the dark.”
- Many other mnemonic songs also use the same technique: “If numbers have heaven / They must have gods / 3.14159 / 26535.”
- ABC tune, also known as “Black Sheep Baa-Baa,” or “Sparkling Little Star”: 3 1 4 1 5 9 2 / 6 5 3 5 8 9 / 7 9 3 2 3 8 4 / 6 2 6 4 3 3 8 / 3 2 7 9 5 0 2 / 8 8 4 1 9 7 1
- Try writing a good rhyme song to help you remember. [3] XResearch Sources .
Advice
- Memorize the digit in the cluster instead of one at a time.
- It helps to think about the numbers in your head before going to bed or getting in the car.
- Adding a little rhythm to the number makes it easier to remember.
- Write it down on a little memory card and whenever you sit down on it, take it out and memorize a little more.
- Set goals and (if possible) exceed plans.
- Pick a song you know and beat the digits of pi with it.
