STEPS

Ask your friend to think of a num­ber 1-10 and it has to be a whole num­ber. (It doesn't have to be 1-10 it can be any num­ber; it also works with dec­i­mals and nega­tives!) Tell them to mul­ti­ply the num­ber by 2. Tell them to add by an EVEN num­ber like 10. Have them di­vide the sum by 2. Have them sub­tract by the orig­i­nal num­ber they thought up. The an­swer should be half of the num­ber that you told them to add if they did the math cor­rectly.
