Math Notes

Teaching math online can be a challenging task, especially for educators who are used to traditional classroom settings. However, with the right tools and techniques, it is possible to create a successful and engaging online learning environment for students. In this guide, we will explore some strategies for teaching math online and share tips for creating effective lesson plans, incorporating interactive activities, and facilitating student engagement and participation.

Componendo Dividendo Rule: The componendo dividendo rule is a useful technique used to solve certain equations involving fractions. It involves adding the numerator and denominator of a fraction on one side of the equation and subtracting them on the other side, which helps to simplify the expression and solve for the unknown variable.

The long division method for square root is a technique used to find the square root of a number. It involves dividing the number into groups of two digits, starting from the right, and finding the largest digit whose square is less than or equal to the current dividend. The process is repeated until the desired level of accuracy is reached.

The mean proportion is a term used in mathematics to describe the middle number between two other numbers in a sequence. To find the mean proportion between two numbers, you simply take the square root of their product. This article provides step-by-step instructions on how to find the mean proportion using this formula. 

The additive inverse of a rational number is the opposite of that number, such that when the two numbers are added together, the sum is zero. This article explains how to find the additive inverse of a rational number, both algebraically and using a number line. It also provides examples to help illustrate the concept.
