Chapter 5
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:
• A variable name: 'a', 'ux', 'width', etc.
• An expression:
• An equation:

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 (EQW).
For example, to enter the algebraic object ' *D^2/4' directly into stack
level 1 use:
³„ì*~dQ2/4`
An algebraic object can also be built in the Equation Writer and then sent
to the stack, or operated upon in the Equation Writer itself. 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):
Page 5-1
12.3, 15.2_m, ' ', 'e', 'i'
'p*D^2/4', 'f*(L/D)*(V^2/(2*g))',
'p*V = n*R*T', 'Q=(Cu/n)*A(y)*R(y)^(2/3)* So'
