2-2

If you mean the arithmetic problem 2 − 2, the result is 0.

If this was part of a larger problem, please share the full statement and I’ll walk you through it.

Want a quick set of similar practice problems? Here are a few:

• 3 − 2 = ?
• 5 − 5 = ?
• 7 − 9 = ?
• 12 − 4 = ?
• −4 − 3 = ? (if you’re practicing integers)

I can tailor more problems to your exam topic if you tell me the subject (algebra, calculus, etc.).
