2+2=5?

No. In standard arithmetic, 2 + 2 = 4.

A quick check:

• Counting: two objects plus two objects gives four objects.
• In basic axioms (Peano-like), 2 = S(1); then 2+2 = S(S(1)) + S(S(1)) = S(S(S(S(1)))) = 4.

If you’re curious, there are contexts where statements like “2+2=5” are discussed (e.g., as a propaganda example in Orwell’s 1984 or in modular arithmetic where results wrap around), but not in ordinary arithmetic. Want a short example in modular arithmetic or a quick explanation of the Orwell reference?
