👉 In mathematics, a lemma is a statement that has been proven to be true without proof. Lemmas are often used as a starting point for proofs and can help to simplify or clarify complex mathematical concepts. They are typically proven using other known facts in the field of mathematics, rather than being derived directly from an existing theorem. For example: 1. If n is an odd integer, then n^2 + 5n - 6 is always greater than zero. 2. If a and b
