2-3

Do you mean 2 − 3 or the interval 2–3? Here are both quick notes:

• Subtraction: 2 − 3 = −1
• Interval notation: “2–3” could mean the range from 2 to 3 (e.g., [2,3], (2,3), etc.). If you have a specific problem (like a definite integral ∫ from 2 to 3 or a probability range), share it and I’ll tailor the steps.

Which one did you have in mind? If you provide the exact problem, I can walk through the solution.
