Mnemonic devices help you to retrieve what you have learned and to hold arbitrary information in memory.

Mnemonic devices may work quite well in some areas of study, but I do not recommend mnemonic devices for mathematics because:

• What you are trying to remember is not arbitrary.

• The mnemonic device obscures the math concept.

• The mnemonic device obscures connections and context.

• The mnemonic is harder to remember than the math.
