Ok, this is how this will work:

I give a math problem.
The next person must then answer my problem correctly. Then they post a math problem, and so on and so forth. Pretty simple.

Here we go:

1 + 1 = ?
^^^^^^
Do exacly above, except different numbers, and you can do multiple numbers/signs/etc., just have one "?" to become the answer next, OK?

1 + 1 = ?
