Multiply by drawing lines!
This might be vedic math from India.
Maybe from Japan.
Who knows - let me know in the comments!
This is a great visual way of seeing multiplication - and because it does not use any multiplication tables, it makes it accessible to all learners.

Exponent notation (also called index notation) is a shorthand way of writing repeated multiplication. The base is the number that is being multiplied and the exponent (index) is the number of time it is multiplied.

Trigonometry is an easy way to work out the unknown sides and angles of a right angled triangle. The trick - know the side names - the opposite, hypotenuse, and adjacent, and know how and when to apply the trigonomic functions - sin, cos and tan. this is the only trick to getting it right every time!
In this lesson, students learn work out unknown angles using use sine, cosine, and tangent. You will need a scientific calculator for the problems in this lesson - and I'll show you how to access one on your computer.

In this lesson, you will learn to multiply fractions quickly and easily.
To multiply fractions you multiply across the numerators (the top number of a fraction) and multiply across the denominators (the bottom number).

An example I always use to start this off is multiply 1/2 with a 1/2. The numerators multiply to give 1 (1 x1), the denominators multiply to give 4 (2x2). Hence a 1/2 multiplied by a 1/2 is 1/4.

What about if you multiply 2/3x1/4?
Top number (2x1), bottom number (3x4).
So 2/3x1/4 = 2/12. To donate to the tecmath channel: https://paypal.me/tecmath?locale.x=en_AU To donate to the tecmath channel: https://paypal.me/tecmath?locale.x=en_AU
