#5 HAND CALCULATOR by Raymond Blum (and others)
Your friends are amazed when you magically transform your hands into a calculator and multiply on your fingers!
Materials
Pen
Preparation
Draw these calculator keys on your palms with a ballpoint pen.
Presentation
Tell your friend that she can multiply by 9 on your hands just as she would on a regular calculator. After she enters the numbers and pushes [=] , just bend over the finger that is multiplied by 9. The fingers that are standing up tell her the answer!
I learned this trick in middle school. I found it very helpful. I hope you do to.
