Math Magic Trick - Number 9
Hello all! For today, I have a fun little video that you can learn to impress you friends, family, or significant other. All the math lovers will probably know this magic trick but I'm sure they'll appreciate that you showed them a math trick.
Steps for this magic trick:
1.) Think of a number between 1-9 (inclusive) and don't tell me the number
2.) Multiply it by 9
3.) If it is a 2 digit number, add the digits together. If it is a 1 digit number, skip this step.
4.) Subtract 5 from your number
5.) Multiply the result by itself
The answer is 16. Was I right? I should be unless you messed up a step somewhere along the way. In this video, I also reveal why this math trick works and how it works. Aside from 1-9, this also works for number 10. Remember, this math magic trick does not work for all numbers. If you like these types of videos on math tricks, let me know in the comments below.
