Divisibility Tests of 1 to 10

Math Animations on Instagram: "Divisibility rules give you a quick way to see whether a number can be divided by a small integer without actually doing the division. For two you simply look at the final digit and if it is even then the whole number is even. For three you add all the digits and if that total divides by three then so does the original number. To test for four you treat the last two digits as their own number and see whether that divides by four. Five is even simpler: any number ending in zero or five will divide by five without a remainder. When you want to check six you apply the rules for two and three – a number that meets both will divide by six. The rule for seven asks you to double the last digit and subtract it from the number formed by the remaining digits; if that result divides by seven then the original number does too. For eight you look at the last three digits and see if they divide by eight. Nine works like three but with nine instead – if the sum of the instagram.com

Logarithm Rules

MA - Basic Algebra on Instagram: "The logarithm is a mathematical concept that represents the inverse of the exponential function. It answers the question of what power a given base needs to yield a certain number. This principle makes it an important tool for analyzing exponential growth or decay processes that occur in science, technology, and economics. In addition, the logarithm facilitates complex calculations because it converts multiplication into addition and exponentiation into multiplication. This led to the historical development of logarithm tables, which were indispensable before the spread of modern computers. Its versatile applications range from solving exponential equations to studying scales such as the decibel or Richter scale to analyzing data in statistics and computer science.

Why are prime numbers so important

QuantMarkov on Instagram: "🧠 Why Are Prime Numbers So Important? 🔹 1. Building Blocks of Numbers Every number is made from primes! Just like atoms build matter, primes build all natural numbers. 🔹 2. Unbreakable Patterns They don't follow easy rules—making them mysterious and fascinating for mathematicians. 🔹 3. Backbone of Cryptography 🔐 Your online banking, passwords, and data security rely on the difficulty of factoring large primes. 🔹 4. Used in Nature & Tech From sunflower spirals to signal processing—primes are everywhere. 🔹 5. Quant Finance 💹 Primes help in creating pseudo-random number generators, essential for Monte Carlo simulations in option pricing and risk models. 🔹 6. Infinite & Irregular There are infinitely many primes, but no formula predicts them all. That's why they're still being studied! ✨ Prime numbers aren't just math—they're magic hiding in plain sight. #crypto #cryptocurrency #bitcoin #blockchain #ethereum #cryptotrading #university #wallstreet instagram.com

Gauss Summation

MA - Algebra on Instagram: "The story behind this formula is as fascinating as the formula itself. The young Carl Friedrich Gauss, a mathematical genius, discovered this formula at around the age of seven. Legend has it that his teacher kept the class busy by asking them to add all the numbers from 1 to 100. While the other students laboriously tackled the problem, Gauss immediately recognized a pattern. He noticed that the numbers could be divided into pairs that each added up to the same sum: 1 + 100, 2 + 99, 3 + 98, and so on. Each of these pairs added up to the same number. This led Gauss to realize that the problem could be solved much faster by multiplying the number of pairs by the sum of one pair. This enabled him to find the solution almost instantly. This insight led to the development of Gauss's formula, which is now a fundamental method in mathematics. It shows how complex problems can be solved in an elegant way by recognizing patterns and symmetries. The formula is an instagram.com
