The process of determining if something is true is fundamentally about checking the accuracy of a claim, proposition, or condition. This is often the case in mathematics, where you'll use logical analysis, pre-established axioms, theorems, or proof to validate the correctness of a mathematical declaration, such as an equation, inequality, or rule. It's a crucial procedure in solving problems and the creation of proofs.
