**1. **** Read the instructions cut them and paste them to your wiki. Underline the words that are time markers. **

Think of a 2-digit integer. __Subtract__ from the number the sum of its digits and find the result in the table below. Note that each cell of the table contains a number and a geometric shape. __Concentrate__ hard on the shape that shares a cell with the result of your calculations. __When ready__, press the "Check it!" button ... I guess that the game works only with multiples of 9. When you think a number, and you do the operations, you will always obtain a number multiple of 9, as a result. In conclusion, all cells with multiples of 9, should have the same figure. ** Good **
 * Good... When is the time marker **
 * 2. **** Play and try to explain why the magic trick worked. **
 * 3. ** ** Check the explanation below the trick. Was it the one you were thinking of? Explain. **

Yes, It is the same explanation but, it uses a mathematical explanation which is:
 *  || (10a + b) - (a + b) = 9ª” ||

If you do the operation, you will always obtain a number multiple of 9, for example: 35, a = 3 and b = 5.

(10(3)+5) – (3 + 5) = 27

99, a=9 and b =9

(10(9)+9)-(9+9) = 81

Etc…

To avoid falling into this trick, just have to keep an eye on the figures that have boxes with multiples of 9, which if you notice, always change every time you repeat the trick. ** Super **
