Quick Math Computation - Squaring Any Number

Hello everyone, I hope you enjoy my "math magic trick" videos that help you look and feel smarter because you can compute certain math problems much quicker than others. Last time, I did a video on squaring numbers that end with a 5 and a different video on squaring numbers between 40 to 60. Those were pretty fun videos so if you haven't seen them, you can watch them here:

Squaring #s between 40 to 60: https://rumble.com/vwcf5a-super-quick-math-computation-squaring-numbers-from-40-to-60.html

Today, I'm back with another fun math trick type video. If you're looking to impress your teacher, classmates, or friends; try doing this trick on them. Today's video will cover several examples that you can compute super quickly to impress others. The focus is squaring ANY number. We generalize the rule this time so it works for all numbers, but remember that the more generalized the rule, the longer it will take to do the trick. Compared to multiplying out the numbers fully, this will still be quicker. Just a fun math trick that is explained by the foiling method.

Steps for this trick / shortcut:
Depending on what the number ends with, choose between the two formulas or "tricks".
If the ending number is less than 5, use the (a+b)^2 method. If the ending number is greater than 5, use the (a-b)^2 method. If the ending number is 5, I go over that trick in the previous video.

(a+b)^2 = a^2 + 2ab + b^2
(a-b)^2 = a^2 - 2ab + b^2

This will work easily for numbers less than 100 but the same idea can be applied to numbers greater than 100.
