Multiplying Fractions Is Easy

Welcome to this series of videos on the Addition, Subtraction, Multiplication, and Division of Fractions. Much thought has been given to making each video simple and intuitive for understanding. The basic concepts required to add, subtract, multiply, and divide fractions are clearly explained and illustrated. It is important to get the basics right from the start.
Learn how to add fractions with unlike denominators easily in this simple and intuitive video.
Many online videos show the use of the Butterfly Method to add or subtract a pair of fractions with unlike denominators. The underlying principle for its use is usually not adequately explained in most of these videos keen to show the short-cut 'trick' as a hack. In some cases, the Butterfly Method is NOT the most efficient method to add or subtract fractions with unlike denominators. Without understanding the constraints of the Butterfly Method, students may jump right into using the Butterfly Method without knowing that they would end up with more work in certain cases where an easier method is available.
Moreover, one cannot use the Butterfly Method to add or subtract 3 or more fractions. It cannot also be used for the multiplication and division of fractions. Some students have memorized the Butterfly Method without the correct understanding and used it to multiply 2 fractions together, resulting in wrong answers.

The videos aim to help the user learn fractions with the correct basics.
In the videos, there are no distracting cartoon animations with lengthy narratives. This is to train focus and improve attention span. You'll find adding, subtracting, multiplying, and dividing fractions simple and easy.
The videos cover the following:
1) Add Fractions with Unlike Denominators (Part 1)
This covers the addition of 2 fractions with unlike denominators.
2) Add Fractions with Unlike Denominators (Part 2)
This introduces the method of finding the Least Common Multiple (LCM) to make unlike denominators the same before adding the fractions.
3) Add More Fractions with Unlike Denominators (Part 3)
This covers the addition of 3 or more fractions with unlike denominators. It expands on the method of finding the Least Common Multiple (LCM) to make unlike denominators the same before adding 3 or more fractions.
4) Subtract Fractions with Unlike Denominators (Part 1)
This covers the subtraction of pairs of fractions with unlike denominators.
5) Subtract Fractions with Unlike Denominators (Part 2)
This covers the subtraction of 3 or more fractions with unlike denominators. It expands on the method of finding the Least Common Multiple (LCM) to make unlike denominators the same before subtracting the fractions.
6) Multiplying Fractions
This covers the multiplication of a pair of fractions and the multiplication of 3 or more fractions.
7) Dividing Fractions
This covers how to divide one fraction with another by finding the reciprocal of the dividing fraction, and then multiplying it with the first fraction.
