Numbers:

3.14159 – Pi, normally represented by the Greek letter pi (P) symbol p. Pi is typically used for calculating the area (p x radius squared) or circumference (p x diameter) of a circle. Pi has an infinite number of decimal places, and fascinates mathematicians in calculating pi itself, and memory experts too in memorizing as much of it as possible.

4/4 – Four beats to the bar, the most common rhythm in music.

24/7 – Twenty four hours a day, seven days a week.

72 Rule – More commonly known as the Rule of 72, with variations 69 and 70, these are standard figures used by financial folk in calculating quickly the years required for an investment to double (or to halve) at a given interest rate. Typically 72 is divided by the compound interest rate to give the approximate years. 72 is more popular than 69 or 70 because it is quite reliable and easily divisible quickly by lots of different numbers.

80/20 Rule – The theory that 20% of effort produces 80% of results, and very many similar effects; also known as Pareto Rule or Pareto Principle, after its originator.

86 – ‘Secret’ code used by restaurant and bar staff when refusing service or ejecting a customer from the premises, and more recently referring to a menu item not available, which is sometimes a lie to achieve the first meaning. The term has existed since the early 1900s and no-one knows the true derivation, although increasingly daft ones are suggested.

360 Degree Thinking – A term used for considering all options in business, etc., as opposed to having narrow field vision.

360 Degree Feedback – An appraisal method typically entailing feedback about a manager given by fellow workers.
