Use logical deductions, algebraic manipulation, or known theorems to connect your starting point to your conclusion.
Never go to a TA and say, "I don't get this." Instead, say, "I attempted a proof by contradiction here, but I got stuck on this specific algebraic transition. Is my initial assumption flawed?"

Unlike algebra, where the next step is usually dictated by an equation, proof writing requires strategic intuition. Students often do not know how to start a proof or what definitions to invoke.
