During today's Did You Know, Michelle put our math skills to the test -- and the outcome? Pretty neat...

Check your change in your wallet for loose coins.  Make sure it adds up to less than $1.
Multiply your age by 2.  Add 5 to that number and multiply the result by 50.  Subtract 365.  Add the amount of change. Finally add 115.  The result will be a 4 digit number. 

...The first two digits are your age and the last 2 the amount of the loose change!
