Algebraic and arithmetic operations

An algebraic object, or simply, algebraic, is any number, variable name or

algebraic expression that can be operated upon, manipulated, and combined

according to the rules of algebra. Examples of algebraic objects are the

following:

• A number: 12.3, 15.2_m, ‘π’, ‘e’, ‘i’

• A variable name: ‘a’, ‘ux’, ‘width’, etc.

• An expression: ‘p*D^2/4’,’f*(L/D)*(V^2/(2*g))’

• An equation: ‘Q=(Cu/n)*A(y)*R(y)^(2/3)*So^0.5’

Entering algebraic objects

Algebraic objects can be created by typing the object between single quotes

directly into stack level 1 or by using the equation writer ‚O. For

example, to enter the algebraic object ‘

π*D^2/4’ directly into stack level 1

use:³„ì*~dQ2/4`. The resulting screen is

shown next for both the ALG mode (left-hand side) and the RPN mode (right-

hand side):

An algebraic object can also be built in the Equation Writer and then sent to

the stack. The operation of the Equation Writer was described in Chapter 2.

As an exercise, build the following algebraic object in the Equation Writer:

After building the object, press to show it in the stack (ALG and RPN modes

shown below):

Simple operations with algebraic objects

Algebraic objects can be added, subtracted, multiplied, divided (except by

zero), raised to a power, used as arguments for a variety of standard functions
