2+2=5

In standard arithmetic, 2 + 2 = 4.

Quick check: counting two objects plus two objects gives four objects. You can also see it on a number line: start at 0, move two steps to 2, then two more steps to 4.

Note: "2 + 2 = 5" is a famous phrase used in literature (e.g., Orwell) to illustrate propaganda or false beliefs being accepted as truth. It’s not true in normal math.

If you’re prepping for exams, I can help with quick practice problems or explanations of related topics (e.g., base systems, carry in addition, or common arithmetic mistakes). Would you like a short 5-question practice set or a quick refresher on a specific topic?
