TeXForm gives the representation of the TraditionalForm expression:

Obtain the representation of the expression in StandardForm:

Convert an expression to :

Use ToExpression to convert back to Wolfram Language syntax:

Use ToExpression to convert from to the Wolfram Language:

The following expression will evaluate:

Use HoldForm to convert unevaluated expressions:

Use Export to generate a compilable document:

When an input evaluates to TeXForm[expr], TeXForm does not appear in the output:

Out is assigned the value x², not TeXForm[x^2]:

Even when an output omits TeXForm from the top level, it is not stripped from subexpressions:

The output does not have TeXForm in it:

However, the variable e does have TeXForm in it, which may affect subsequent evaluations:

The product is not evaluated due to the intervening TeXForm:

Assign variables first and then apply TeXForm to the result to maintain computability:
