How to Do the Amazing Math Card Trick | Magic Tricks

Learn how to do the amazing math card magic trick from Magician Roger "Rogue" Quan in this office magic tricks revealed video from Howcast.

Roger "Rogue" Quan: Hey Heather, how about a card trick?

Heather: Cool.

Roger: I just need a number between, I guess 10 and 20. Any number you want.

Heather: 18.

Roger: 18. Do you want to change your mind?

Heather: No.

Roger: No. We'll deal out 18 cards, alright? One, two, three, four, five, six, seven, eight, nine, ten, 11, 12, 13, 14, 15, 16, 17, 18. That's pretty fair, right? Let's randomize this a little bit more. 18 consists of two numbers, one and eight. What's one plus eight?

Heather: Nine.

Roger: Deal down nine cards. One, two, three, four, five, six, seven, eight, nine. Actually, memorize that card. Got it?

Heather: Mm-hmm.

Roger: I'm gonna read your mind. It's a black card, correct? It's a club. It's an odd card. The number, it's a little low, pretty low. It's a three of clubs.

Heather: Yeah.

Roger: Awesome.

Okay, here's the secret to the math card trick.

Basically, you need a regular deck and you have to memorize the card at the tenth position. So One, two, three, four, five, six, seven, eight, nine, ten. In this case, the five of clubs.

You have to kind of force this card on your spectator without them knowing.

So that's the tenth card from the top of the deck. You have them name a number between ten and 20. So any number from 11 through 19 will work.

So let's pretend the card is 12. You deal down from the top. One, two, three, four, five, six, seven, eight, nine, ten, 11, 12.

Now you're gonna tell them they're gonna randomize the trick a little bit more. You're going to have them add up the two numbers that make up 12, which equals three actually. One and two equals three.

And they're going to deal from the smaller pile. One, two, three. They memorize this card. That happens to be the five of clubs. The card that you actually know in your mind.

So basically what happens now is you're going to read their mind any which way you want. I like to do it nice and slow. I tell themm, "Your card is a black card, it's a club, it's a number card, it's little bit low, it's the five of clubs."

It's an amazing trick that you can do for your friends.

And that is the math card trick. Have fun, guys.

To make this card trick even more amazing let the other person hold the cards and control them throughout the trick...have them mix as good as they want and then tell them to flip them one by one as quick as they can exposing each card to you and just remember the 10th card and tell them you have a super memory and can remember the entire 52 card deck and then just have them complete the rest of the trick with your direction with them handling the cards the whole way until you predict the card at the end....makes it so so so much more amazing!!!
