<s>[INST] As a mathematics student, I find myself facing a paradox. It is the well-known liar paradox, which can also be expressed in mathematical terms. Below is what is causing me the trouble:

"There is a statement that says, 'This sentence is false.' If it is true, then it must be false, but if it is false, then it must be true."

Now, my question to you is: How do I deal with this paradox within the context of mathematics?[/INST]
