Chapter 2
Introducing the calculator
In this chapter we present a number of basic operations of the calculator
including the use of the Equation Writer and the manipulation of data
objects in the calculator. Study the examples in this chapter to get a good
grasp of the capabilities of the calculator for future applications.

Calculator objects

Some of the most commonly used objects are: reals (real numbers, written
with a decimal point, e.g., -0.0023, 3.56), integers (integer numbers,
written without a decimal point, e.g., 1232, -123212123), complex
numbers (written as an ordered pair, e.g., (3,-2)), lists, etc. Calculator
objects are described in Chapters 2 and 24 in the calculator's user guide.

calculator display or stack.
