2-2

Do you mean the arithmetic expression 2 − 2? If so, the result is 0.

If this was meant as a section/problem reference (e.g., Section 2, Problem 2) or a different subject, please share the full problem statement and the course topic, and I’ll help with a step-by-step solution.

Would you like me to create similar subtraction problems for practice? Here are a few with solutions:

• 7 − 3 = 4
• -5 − 2 = -7
• 2 − (-5) = 7
• -1 − (-4) = 3
• 0 − 9 = -9

If you provide the exact context, I can tailor a detailed explanation.
