Are there scenarios where 1 + 1 does not equal 2?
In pretty much all instances, 1 + 1 does equal 2, right? One apple plus one apple, one dog plus one dog, it all equals two. But are there times when one plus one does not equal two? Maybe in a chemical solution, you add two types of molecules, and the result is only 1.5 times the molecule, or something like that?

I believe that you have to really sit back and look into this. Yes there are situations where 1+1 might not always come to 2. Of course this lies precisely in scientific reasoning and not in math occurrences. I think the best example lies in child birth. 1 parent + 1 parent doesn't always mean 2 children in a pregnancy. It could easily point towards 1 child or in one very famous case up to 8 children in the pregnancy.
