Super Quick Math Computation - Squaring Numbers from 40 to 60

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. That was a pretty fun video in my opinion! If you haven't seen that video, you can watch it here: https://rumble.com/vvmybg-super-quick-math-computation-squaring-5.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 numbers between 40 to 60. It's easy to remember the values of 40^2, 50^2, and 60^2 so that won't be as impressive. We will split the trick into remember different steps for numbers less than 50 or greater than 50. All it takes is more practice then you can do it! This math trick only works for numbers from 40 to 60.

Steps for this trick / shortcut:
If the number is less than 50,
1.) 50 - something = the number you want
2.) 25 - something = another number
3.) something ^ 2
4.) Put the something ^2 at the end of another number

Did I just confuse you? Let me show you in variables
The number you want to square will be represented by x
1.) 50 - y = x
2.) 25 - y = z
3.) y^2
4.) Put it together and you get z(y^2). Note that this isn't multiplication.

For numbers that are greater than 50, it is the same but you add instead of subtract. Add the number to 50 and add the number to 25 in steps 1 and 2.

Just a fun little short video on another math shortcut. I hope you enjoyed it! Thanks for watching! Please drop a like and subscribe to my channel. Don’t forget to let me know if you have any questions in the comments below.
