In this lesson, Harlan Tarbell explains three tricks that have one thing in common: they involve numbers.

You'll learn principles and tools that you can also use for completely different effects. You'll learn, among other things, how to show a labeled card empty, how to subtly force numbers, and how to easily make your own simple yet effective exchange envelope.

Once you have mastered this skill, you will be able to perform a variety of tricks with a mental touch.

Harlan Tarbell's explanations are followed by a bonus appendix written by Werner Miller , which explains in detail an interesting variation of the "magic square" : a 5x5 square formed from all the numbers from 1 to 25, whose rows, columns and diagonals each add up to 65.
