Look what trick I learned on Youtube! I will guess your age!

Pick any number from 1 to 10.

Multiply your choosen number by 2.

Add 5 to your total.

Multiply your new total by 50.

If you have already had your birthday this year, add 1767.
If you have not had your birthday this year, add 1766.

Subtract from your total the year which you were born (e.g. 2003).

Now your total should be a three digit number.
The first number of your total will be the number you chose at the beginning.
The remaining two numbers are your age.

I found this thing on Youtube, and I wanted to show you this math trick! Like this topic if you like this trick.

I hope we realize that subtracting the total from the year you were born is a dead give away for most of the steps being created for needless complexity.

I may or may not have tested that calculation algebraically.
