first glance, the “1 + 2 = 3!” looks like a fun, simple equation — perfect for advertising something “as easy as 1-2-3.” But here’s the hidden joke:
- In normal math, 1 + 2 = 3.
- In math with factorials, 3! means 3 factorial, which is 3 × 2 × 1 = 6.
- So mathematically, the statement 1 + 2 = 3! becomes:
1 + 2 = 6 — which is obviously false. - That mismatch is where the humor comes from — it’s pretending to be simple, but it’s secretly nerdy math humor.
Why It’s Funny
It works on two levels:
- For regular viewers – it’s just a quick, catchy “as easy as 1-2-3” slogan.
- For math-savvy people – it’s a little Easter egg that makes them go, “Wait… but 3! is 6!” and laugh at the absurdity.
