Did you know that the concept of "zero" didn’t always exist in mathematics? It was first used in ancient India around the 5th century, credited to the mathematician Brahmagupta. The word "zero" comes from the Sanskrit word śūnya, meaning "empty." Before its invention, calculations were much more complicated!
Brahmagupta (598–668 CE): An Indian mathematician and astronomer, Brahmagupta, was the first to formalize rules for zero in arithmetic. He described zero as a numeral and established its basic mathematical operations, such as:
0 + x = x
x - 0 = x
x × 0 = 0
He also attempted division by zero but struggled with its interpretation, which remains a unique challenge even today.
Al-Khwarizmi (the father of algebra) and other Islamic scholars translated Indian texts into Arabic, spreading the use of zero throughout the Middle East. The Arabic numeral system, which included zero, became widely adopted.
Back to TopThe value of π (3.14159…) has fascinated mathematicians for thousands of years. The ancient Egyptians and Babylonians approximated it over 4,000 years ago. However, the Greek mathematician Archimedes was the first to calculate π accurately, using geometry.
Back to TopThe Fibonacci sequence (1, 1, 2, 3, 5, 8, 13…) isn’t just a math concept—it appears everywhere in nature! From the spiral arrangement of sunflower seeds to the number of petals in flowers, this sequence is nature’s favorite pattern.
Back to TopThe famous Pythagorean Theorem (a² + b² = c²) was developed by the Greek mathematician Pythagoras, but it was actually known to the Babylonians over 1,000 years earlier! Pythagoras also believed numbers held mystical properties and founded a school based on the study of numbers.
Back to TopPrime numbers (like 2, 3, 5, 7, 11…) are the "building blocks" of mathematics because every number can be expressed as a product of primes. Even today, mathematicians don’t fully understand their distribution, making them one of math’s biggest mysteries!
Back to TopTry this:
1. Pick any three-digit number where the first and last digits differ (e.g., 321).
2. Reverse the digits (123).
3. Subtract the smaller number from the larger number (321 - 123 = 198).
4. Reverse the result (891).
5. Add the two numbers (198 + 891 = 1089)!
No matter what number you start with, you’ll always end up with 1089. Magic? No, it’s math!
Back to TopThe largest known prime number as of today is a Mersenne prime, discovered in 2018. It has a mind-boggling 24,862,048 digits! Such discoveries are made using powerful computers and help advance cryptography and security.
Back to TopThe Cake-Cutting Problem is a famous mathematical puzzle about how to divide a cake fairly among people. Mathematicians have even developed algorithms to ensure everyone gets an equal and envy-free slice—no fighting needed!
Back to TopThe ancient Egyptians were incredible mathematicians! They used a base-10 system and fractions to build the Great Pyramids of Giza. Their system was so advanced that it allowed them to perform engineering feats that still amaze us today.
Back to Top• Googol: A googol is the number 1 followed by 100 zeros! It was named by a 9-year-old boy and inspired the name of the search engine "Google."
• Infinity (∞): This symbol was first used by the mathematician John Wallis in 1655. It represents a number without an end!
Back to TopIs "1" a prime number? While it seems like it should be, it isn’t classified as one because it doesn’t meet the official definition: having exactly two distinct divisors (1 and itself).
Back to TopPascal’s Triangle, discovered by Blaise Pascal, is a triangular array of numbers where each number is the sum of the two numbers directly above it. It’s used in algebra, probability, and even to predict patterns in nature!
