In the home environment, all numbers are numerically interpret and all calculations executed numerically. For the calculations both the "text book" input mode and the HP-typical "RPN" input mode are available.

Over one hundred mathematical functions are already available directly from the keyboard.
Many other math functions are in the Math Menu, that has been divided in several sections:

• Numbers:
  Rounding numbers.
• Arithmetic:
  Calculate maximum, minimum, dividing radicals and percentages.
• Complex numbers:
  Calculating real part, imaginary, conjugated, arguments and unit vectors.
• Trigonometric Functions:
  CSC, ACSC, SEC, ASEC, COT, ACOT.
• Hyperbolic Functions:
  SINH, ASINH, COSH, ACOSH, TANH, ATANH.
• Probability:
  calculating faculties, combinations, permutations, random numbers and of probabilities for normal, binomial or Poisson distributions.
• Lists and matrices:
  Creating lists (or matrices) and execute functions on these lists (or matrices).
