63: This is the part which performs basic algebraic operations,
64: such as arithmetic operations, to algebraic objects, e.g., numbers and
65: polynomials, which are already converted into internal forms.
66: It exists, like @samp{libc.a} of UNIX, as a library of ordinary UNIX system.
67: The algebraic engine is written mainly in C language and
68: partly in assembler.
69: It serves as the basic operation part of @b{Asir}, a standard

739: In the above example, names @code{A}, @code{a}, @code{x} and @code{y}
740: are used to identify mathematical and programming objects.
741: There, the name @code{A} denotes a program variable
742: (some times called simply as a program variable.)
743: while the other names, @code{a}, @code{x} and @code{y}, denote
744: mathematical objects, that is, indeterminates.
745: In general, program variables have names which begin with
746: capital letters, while names of indeterminates begin with
747: small letters.
748: As you can see in the example, program variables are used to hold and
749: keep objects, such as numbers and expressions, as their values,
750: just like variables in C programming language.
751: Whereas, indeterminates cannot have values so that assignment to
752: indeterminates are illegal.
753: If one wants to get a result by substituting a value for an indeterminate
754: in an expression, it is achieved by the function @code{subst} as the
755: value of the function.
