Appropriate for Grades 3 and up (people who know their 2 times tables and 5 times tables)!
Tell your friend to pick their favorite number between 1 and 100, but don't tell you what it is!
Note: If your friends are children, have them pick a number between 1 and 9 so they are able to do the next steps. If you're doing this with mom and dad, you can tease them and make them pick REALLY big numbers so they have to work hard at the math. They'll be very surprised when you come back with the answer so quickly!
Have them multiply their number by 2.
Have them multiply their number by 5.
Have them tell you the answer they've come up with.
Drop the zero from the answer they gave you and tell them what their number was!
