===Life insurance===
The basic symbol for a [[life insurance]] is <math>\,A</math>. The following notation can then be added:

* Notation to the top-right indicates the timing of the payment of a death benefit. A lack of notation means payments are made at the end of the year of death. A figure in parentheses (for example <math>A^{(12)}</math>) means the benefit is payable at the end of the period indicated (12 for monthly; 4 for quarterly; 2 for semi-annually; 365 for daily).
* Notation to the bottom-right indicates the age of the person when the life insurance begins.
* Notation directly above the basic symbol indicates the "type" of life insurance, whether payable at the end of the period or immediately. A horizontal line indicates life insurance payable immediately, whilst no mark above the symbol indicates payment is to be made at the end of the period indicated.

For example:

<math>\,A_x</math> indicates a life insurance benefit of 1 payable at the end of the year of death.

<math>\,A_x^{(12)}</math> indicates a life insurance benefit of 1 payable at the end of the month of death.

<math>\,\overline{A}_x</math> indicates a life insurance benefit of 1 payable at the (mathematical) instant of death.
