Delayed Simplification for Certain Built-In Functions
Usually, variables are automatically simplified to their lowest possible level before they
are passed to a function. For certain functions, however, complete simplification is
delayed until after the function is performed.

Functions that Use Delayed Simplification
Functions that use delayed simplification have a required var argument that performs the
function with respect to a variable. These functions have at least two arguments with the
general form:
function(
expression, var
[, ... ]
)
Note:
Not all functions that use a var argument use delayed simplification.
For a function that uses delayed simplification:
1. The
var
variable is simplified to the lowest level at which it remains a variable (even if
it could be further simplified to a non-variable value).
2. The function is performed using the variable.
3. If
var
can be further simplified, that value is then substituted into the result.
For example:
solve(x^2
