How to square any numbers in your head - fast mental math trick here: https://www.youtube.com/watch?v=GEuyDHMG0jY

There is barely any calculation needed to mentally find the square a number that ends in five. How fast? The square of 45 is 1225; The square of 85 is 7225; the square of 115 is 12125; the square of 1095 is 1188125....as fast as I can type them I answer them!
The trick is this to faster squaring....
Say we have 65 squared. Get the number that is not 5 ( that is 6) and multiply it by the next number after it (7). Then just write 25 on the end.
So 6 x 7 = 42, our answer is 4225. Really. Simple 'eh?

In the video lesson, you will learn how to convert a number from standard notation to scientific notation by moving the decimal place. By doing this really big numbers and really small numbers can be easily described.
e.g to write 470,000 in scientific notation, write the number 4.7, (so that there is only one digit to the left of the decimal point), then count the number of places that the decimal point must be moved to get back to 470000 ( in this case is 5). If the number is big it is a positive exponent (like this one - which we'd write as 4.7 x 10^5).
A little number - like 0.0000033 gives a negative exponent (in this case 3.3 x 10^-6).

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
