2-2 is nothing, times 2 is still nothing, which leaves 1.

-3 watch your order of operations
We suck. It look's like Arvid was the only one not sleeping in math class. :)

My answer to the question would have to be 'no', but I've had 38 years to make up for it. And I think Arvid has it.
Zero - you cannot multiply by zero and get anything but zero.
The order of operations is:
BODMAS
(Brackets, Of, Division, Multiplication, Addition, Subtraction )
And I was taught that when I was 10 or 11 if not before !
As there are no brackets changing the order, the answer can only be -1
You have the D and M switched from what I learned. We learned the last 4 stood for "My Dumb Ass Sister". Either way, M & D carry the same weight, as do A & S, so both ways are correct.
I came up with the same thing as Greg until I was reminded that subtraction is actually addition of negative numbers. Here's how Quora explains it:
2-2*2+1
Separate each number with corresponding sign
(2)+(-2)*(2)+(1)
then
(2)+(-2*2)+(1)
=>(2)+(-4)+(1)
=>(2)+(-4+1)
=>2+(-3)
=>2–3
=>-1
Even tho -3 makes more sense!
