Multiplication Done Quickly - Math Magic Trick EXPLAINED
Hello there! For today's video, I talk about a different approach to computing multiplication problems. The standard method that we learned in school for multiplication was to physically multiply all the numbers out and line up the digits, this is called long multiplication. This was the traditional method on multiplying numbers. Today, I go over a math magic trick, a different way to see multiplication. You will need to know how to square numbers really quickly, so if you haven't seen that video already, check it out here: https://rumble.com/vxjjo4-quick-math-computation-squaring-any-number.html
First thing you need to check is whether or not the two numbers you are multiplying together are either both odd or both even. This rule only applies if the two numbers are both odd or both even. The difference between the two numbers will always be even in these cases.
We can rewrite the numbers into (a+b) • (a-b) which is a^2 - b^2. The b is half of the difference between the two numbers. By breaking it down, you can quickly compute the multiplication problem. Initially, this method may seem a bit daunting but with practice, this will be a great trick to use when trying to impress your classmates or your family.
