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, PINs, 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.
