At the time I'm writing, Ms Help gave the best answer and I'd follow it if I were you. However, if you want to focus on mathematics, you should just think 1+1=2 is true only using some unities/base numerations (maths has a lot, not only the ones we expect to use daily). 1 in ten-based numeration means 0 in the two-based one, as well as 1 in two-based numeration is the same as 2 in the ten-based one... :) mathematics is a huge mystery...

Hi, Adam. I think you can definitely emphasize the fact that under certain circumstances, 1+1doesn't equals to 2. Cause the topic is 1+1=2?, there is one question mark there. That definitely gives us a good reason to raise a dispute on the equation. And agree with you on integrity will make the group more competitive and disputes will make the group less powerful.
