Actuarial notation is a shorthand method to allow actuaries to record mathematical formulas that deal with interest rates and life tables.
The core alphabet includes familiar letters such as <math>i</math> for the effective rate of interest, <math>v=(1+i)^{-1}</math> for the discount factor, <math>\delta</math> for the force of interest, <math>l_x</math> and <math>q_x</math> for life table entries, and function letters such as <math>a, \ddot a</math> and <math>A</math> for annuities and insurances.
