2-3

If you meant a simple arithmetic problem: 2 − 3 = −1. Explanation: subtracting a larger number from a smaller one gives a negative result. On a number line, start at 2 and move 3 units left to reach −1. If you meant something else by "2-3" (e.g., a range from 2 to 3, or problems labeled 2 and 3 in a set, or chapters 2–3), please clarify and I’ll tailor the help. I can also provide a quick negative-number practice set or step-by-step solutions.
