Description from the Publisher
Do you sometimes feel embarrassed because you cannot recall a phone number? Try an alternative way to memorize phone numbers.
Look at your cellular phone. Note that several letters correspond to the figure on each button.
Only 1 and 0 have no letters corresponding to them, but only the – and + signs.
The program will show you all possible textual variants of the specified number. Select the one that you can memorize better and use it.
