Default Simplification Rules
All of the following rules are applied automatically. You do not see intermediate results.
Default simplification does not modify variables that use path names to indicate a
folder. For example,
x+class\x
does not simplify to 2x.
Note:
For information about folders, refer to the
Calculator Home Screen
module.
•
For functions:
-
The arguments are simplified. (Some built-in functions delay simplification of
some of their arguments.)
-
If the function is a built-in or user-defined function, the function definition is
applied to the simplified arguments. Then the functional form is replaced with
this result.
•
If a variable has a defined value, that
value replaces the variable.
If the variable is defined in terms of
another variable, the variable is replaced
with its “lowest level” value (called infinite
lookup).
•
Numeric subexpressions are combined.
•
Products and sums are sorted into order.
