context_page_description: Casio V.P.A.M. calculators are scientific calculators made by Casio which use Casio's Visually Perfect Algebraic Method, Natural Display or Natural V.P.A.M. input methods.
  V.P.A.M. is an infix system for entering mathematical expressions, used by Casio in most of its current scientific calculators. In the infix notation the precedence of mathematical operators is taken into account. According to Casio, in V.P.A.M. calculations can be input exactly as they are normally written. Functions, operators and symbols are shown on the calculator display and calculations are performed according to operator precedence.
