Math Class Magic: The Lucas Fan (Binary System)

A classic mathematical "magic trick" designed by French mathematician Édouard Lucas in the 19th century. With these 5 simple strips, you can guess any number between 1 and 31 that a friend thinks of!It is a fantastic STEM educational tool to introduce children (and adults) to the concept of the Binary System in a fun and interactive way.🎩 How to Perform the Magic Trick:Ask a friend to think of a number between 1 and 31.Show them the 5 strips one by one.Ask: "Is your number written on this strip?"If they say YES, keep that strip in your hand. If they say NO, put it aside.Once you have checked all 5 strips, look at the Red Numbers at the bottom of the strips they said "YES" to.Sum them up. The total is exactly the number they thought of!Example:Your friend thinks of 25.Is it on strip 1 (Red 1)? -> YES (Keep it)Is it on strip 2 (Red 2)? -> NOIs it on strip 3 (Red 4)? -> NOIs it on strip 4 (Red 8)? -> YES (Keep it)Is it on strip 5 (Red 16)? -> YES (Keep it)Calculat
