👉 Circular math, also known as circular reasoning, is a logical fallacy where the conclusion of an argument is used as one of its premises, essentially looping back on itself without providing independent evidence. This creates a closed loop where the argument's validity relies solely on its circular structure, rather than on external facts or logical reasoning. For example, "God exists because the Bible says so, and we know the Bible is true because it's the word of God," uses circular reasoning: the truth of the Bible (premise) is used to prove God's existence, which in turn proves the Bible's truth (premise), thus making the argument self-referential and logically unsound.
