What's New
Updated app icon. Removed usage of the obsolete UIWebView element.
App Description
Using this app you will learn to do some multiplying of small numbers (till 12) without using the multiplication tables.
This app presents only a part of the Trachtenberg system - a new way to do basic multiplication. The important benefits of this system are greater ease, greater speed, and greater accuracy. The Trachtenberg system, once learned, can take the drudgery out of the arithmetic that is part of your daily stint.
