Studentathlete should have used the rounding argument.

And this debate will become some semantics mess.

It is impossible to make the debate "fair." Whichever way the rules go, so goes the winner, all but regardless of skill :).

Ragnar, to make this debate fair, we must ensure that
1a+1a=1b is irrelevant
1a+1a=1a is relevant.
1a+1b=1a+1b is irrelevant.

If all of the symbols take on their most common mathematical meaning, then 1+1 always equals 2. PRO should win this debate easily, though, because there are a number of contexts in which this isn't true, and he never specified that this debate is limited to the scope of mathematics.

Those are non-additive phenomena, Wjm, so they can't be considered incidents of 1+1.

What can be considered incidents of 1+1 not equalling 2, are such things as I described here:

It's a trap:
1 pile of sand + 1 pile of sand = 1 pile of sand
1 square + 1 circle = 1 square + 1 circle

No one is going to accept this. They know it's a trap. It is very rude to expect people to agree to lose a debate.

This isn't worth debating to find out what silly trick is proposed. 1+1=2 is a purely mathematical abstraction that is true as defined in the world of mathematics. Whether or not it applies to a particular situation in the real world has nothing to do with the math, it has to do with the art of applying math.
