MATHOMATICS





This is a card trick I find very useful when a spectator makes it impossible for you to do the trick.I call the trick ,Mathomatic.

Mathematical discovery-- ask a person to choose a card. tell him to remember it's numerical value (ace = one, jack- = 11, queen = 12, king = 13) ---also the suit of the card.

Tell them to double the value of the card

Then tell them to add three to the total

Then tell them to multiply the complete total by five

This done ask them to concentrate on the suit

If the card is a diamond they must add one

If the card is a club they must add two

If the card is a heart they must add three

If the card is a spade they must add four

They must then tell you the final total

From it you immediately know the chosen card

The secret is to mentally subtract 15 from the given total--you will have a number of two figures- possibly three

The last figure gives you the suit(diamonds 1, clubs 2, hearts 3, spades 4.) while the first figure gives you the suit.

Example: Jack of clubs

11 doublesd is 22, add 3--25, multiply by 5--125. add for clubs--makes 127. You are told that number

Subtract 15 mentally. result 112. last figure (2) means clubs, first figure(11) means jack.
