1. The problem is to remove the dollar signs from a given expression or text. 2. Dollar signs are often used to denote math mode in LaTeX, but here we want to remove them. 3. For example, if the expression is $x + y = z$, removing dollar signs gives x + y = z. 4. This is simply a text replacement task: delete all occurrences of the character $. 5. There is no mathematical operation involved, just removing the symbol. 6. Final answer: the expression without any dollar signs.
