^Introduction - How to Remember Numbers\

Of all the areas concerned with memory, the most difficult category to
remember is, without doubt, numbers.

Numbers are completely %abstract\ and %intangible\ - they cannot be pictured
in the mind.  They are also some of the most important things that people
have to remember - telephone numbers, PIN numbers, addresses, credit card
numbers, prices, bank account numbers, statistics, dates - the list goes on
and on.

Fortunately, the chore of remembering numbers can be made easy by learning a
simple >Phonetic Alphabet\, which substitutes letters for numbers.  Using
this system, numbers can be transposed to letters and then words, which can
be pictured, and therefore memorised.

Tutorial 8 explains the rules of the Phonetic Alphabet, and how digits can
be transposed into letters.  Tutorial 9 shows how a string of digits can be
transposed into words.  Finally, Tutorial 10 demonstrates how |any\ long -
digit number can easily be memorised, by combining the rules of the Phonetic
Alphabet with two of the memory systems you have already learned - the Link
system and Association of Ideas.~
