This is a pretty cool birthday math trick! This math trick will involve some math calculations so be sure the person does the math correctly (may need to use a calculator).
Note: Make sure you try this trick out for yourself first, using your own birthdate.
STEPS TO THE MATH TRICK
Here's an example below...
Let's suppose someone has a birthdate of August 22, 1964.
So we want to use the format of month/day/year so this birthdate would be08/22/64.
Notice we only used two digits for the year.
