Hi all, Just wondered if any of you do routines like I use to do when first performing ,I got into magic after using little math puzzles on my students to make the classroom thoery lesson more intresting,I have made up routines and named them after film themes, ROOM 1408 ,KNOWING ,just to name a few ,I get a good response when they break the code to the safe and its full of sweets, or I put a timer in ,and BOOM they have not broken the code in time,just a few ideas of mine ,proberly all been done before ,just wanted to share.

Sounds great. I'm not sure who you are. But you were certainly not my maths teacher, who was about as creative as a house fly.

I would be interested to hear more about which theories and what effects that you are using.

I also teach math

1089 is a good one, and there are many more, with use of good imagination it is possible to get the whole class buzzing.

Jim Steinmeyer has used what he calls the "half 1089" principle - the idea that, after the first step, the digit of the number you get (594, 396, 99, or whatever), the digits will always add up to 18, and the digit in the 10s place will always be 9.

Speaking of Jim Steinmeyer, his Impuzzibilities series of books are great sources for mathematical magic!

My "Reversal Plus" ebook describes a new extension of the reversal (1089) principle that lends itself well to mentalism applications.

Arh yes the same principle in the BIP book 2.0 all add up to 18 ,there is another equation I use after the student's have done a little multiplication and put in a 4 digit number I subtract 250 from there number and crack the combination that they set in a box ,all good fun.

I believe that Martin Gardner has a number of math type of magic effects in his books,...
