Overview of Calculator

  Calculator performs arithmetic functions including addition,
  subtraction, multiplication, and division.  Calculator
  also calculates percentages and square roots, performs
  trigonometric and inverse trigonometric functions, and
  determines logarithmic calculations.

  Calculator has three modes:  decimal, hexadecimal, and octal.
  Each mode contains unique keypad and special functions.

  Unlike handheld calculators, the online calculator has two
  displays.  The top display is the accumulator and the bottom
  display is the memory.

  Enter data by moving the pointer to a button in the
  Calculator display and clicking MB1 or by typing at the
  keyboard.  If you type at the keyboard, you can use the
  number keys on the keyboard or the number keys on the
  keypad.
