Ha! I know what you did!
If you're thinking it somehow squared the 6.66, you're right. But there's no way the above sum would lead to that, even if the multiply button was registering a phantom double click (like my POS Logitech mouses).
To square something, you hit X X =
Even if I was hitting 3 X X 2, it still wouldn't square anything. You have to hit equals directly after the two multiplies. In fact if you hit 3 X X 2 on a calculator, it's just going to give you 6.
