A check mark (or tick) is a symbol ✅ used to indicate 'yes,' 'correct,' or 'completed.' Think of it like a visual thumbs-up 👍. It's the opposite of an 'X' which means 'no' or 'incorrect' ❌. You see check marks on to-do lists, quizzes, and forms all the time. It signifies approval or agreement. It's like a digital nod showing something's been taken care of. Imagine it as the green light for success.
