The History of Speed Math

Are you a fan of math? Do you love solving problems quickly and efficiently? Then you might be interested in the fascinating history of speed math! From ancient civilizations to modern-day competitions, speed math has been a part of human culture for thousands of years. In this article, we'll take a look at the origins of speed math, how it has evolved over time, and some of the most impressive speed math feats in history.

Ancient Origins

Believe it or not, speed math has been around for thousands of years. The ancient Egyptians, for example, used a system of hieroglyphs to represent numbers and perform basic arithmetic. They also used a system of weights and measures to solve more complex problems. The ancient Greeks were also known for their mathematical prowess, with famous mathematicians like Pythagoras and Euclid developing groundbreaking theories and formulas.

But it wasn't until the invention of the abacus in ancient China that speed math really took off. The abacus, which consists of a series of beads or stones on a frame, allowed users to perform calculations quickly and accurately. It was widely used in China and other parts of Asia for centuries, and is still used today in some parts of the world.

The Rise of Mental Math

While the abacus was a game-changer for speed math, it was still a physical tool that required some degree of manual dexterity. It wasn't until the development of mental math techniques that speed math truly became a mental exercise.

One of the earliest mental math techniques was the "casting out nines" method, which was developed in ancient India. This method involves adding up the digits of a number and "casting out" any nines until you're left with a single digit. For example, if you add up the digits of 1234, you get 10. If you cast out the nines, you're left with 1. This method can be used to check the accuracy of calculations, and is still taught in some schools today.

Another mental math technique that gained popularity in the Middle Ages was the "chisanbop" method, which originated in Korea. This method involves using your fingers to represent numbers and perform calculations. For example, you can represent the number 7 by holding up your index and middle fingers on one hand, and your ring finger on the other hand. This method is still used today in some parts of the world, and is especially popular among young children.

Modern-Day Speed Math

In the modern era, speed math has become a popular pastime and competitive sport. There are now numerous competitions and events dedicated to speed math, including the Mental Calculation World Cup and the World Mathematics Championships.

One of the most famous speed math feats in recent history was performed by Shakuntala Devi, a math prodigy from India. In 1980, Devi was able to correctly multiply two 13-digit numbers in just 28 seconds, a feat that earned her a place in the Guinness Book of World Records.

Another impressive speed math feat was performed by Scott Flansburg, also known as the "Human Calculator." Flansburg is able to perform complex calculations in his head at lightning speed, and has set numerous world records for mental math. In 2001, he was able to correctly add a randomly generated sequence of 15-digit numbers in just 36 seconds, a feat that earned him a place in the Guinness Book of World Records.

The Future of Speed Math

As technology continues to advance, it's likely that speed math will continue to evolve as well. Already, there are numerous apps and websites dedicated to helping people improve their mental math skills. These tools use gamification and other techniques to make speed math more engaging and fun.

In addition, there are likely to be new techniques and methods developed in the future that will make speed math even more efficient and effective. Who knows what the next Shakuntala Devi or Scott Flansburg will be able to accomplish?


From ancient civilizations to modern-day competitions, speed math has been a part of human culture for thousands of years. Whether you're using an abacus, mental math techniques, or the latest technology, speed math is a fun and challenging way to exercise your brain and improve your math skills. So why not give it a try? Who knows, you might just discover a hidden talent for speed math that you never knew you had!
