Divisibility Rules of of 1 to 10 (aka testing for multiples 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

How to find remainder

How to find reminder using calculator

1. key in the division statement accordingly and hit "="

2. subtract away the whole number portion from the answer (quotient)

3. multiply the decimal (fractional part of the quotient) by the divisor to get the Remainder

Math Animations on Instagram: "Indeterminate forms are expressions that arise when evaluating limits but do not have a clear or predictable value on their own. They often occur in calculus, especially when dealing with functions that approach infinity, zero, or both. An indeterminate form signals that the situation is more complex than it appears and that standard arithmetic rules cannot be directly applied. For example, when both the numerator and the denominator of a fraction approach zero, the result is not automatically zero or any specific value. Instead, we say the expression takes the indeterminate form „zero over zero," and further analysis, such as using algebraic simplification or L'Hôpital's Rule, is needed to find the actual limit. Other common indeterminate forms include expressions like infinity divided by infinity, zero times infinity, or one raised to the power of infinity. These forms are called "indeterminate" because they can lead to many different outcomes dependin instagram.com

Beauty of Mathematics — Maxwell Equation

𝗣𝗶 𝗠𝗮𝘁𝗵𝗲𝗺𝗮𝘁𝗶𝗰𝗮 | 𝗠𝗮𝘁𝗵 𝗦𝗶𝗺𝗽𝗹𝗶𝗳𝗶𝗲𝗱 on Instagram: "James Clerk Maxwell used Faraday's law of electromagnetic induction as one of the key components in developing his electromagnetic field equations. Maxwell realized that by combining Faraday's law with Ampère's law he could unify electricity and magnetism into a single theory – electromagnetism. Faraday's law states that a changing magnetic field induces an electric current, while Ampère's law relates the magnetic field to electric currents. By incorporating these two laws into his equations, Maxwell was able to show that electric and magnetic fields are interconnected and can be described by a set of differential equations, known as Maxwell's equations.
