Is this viewpoint valid, or is any argument which cannot be summed up in numbers not valid.

You'd be closer if you replaced "truth or false" with "validity or invalidity".

Isn't mathematics surely a branch of logic?

Yes, that's the usual classification.

"Today, logic is both a branch of mathematics and a branch of philosophy." http://plato.stanford.edu/entries/logic-classical/ <unsnip> I liked that explanation for where I thought the exchange was leading, so adopted its terminology.
He asked if math was a branch of logic.
You said yes, but then you said that logic is a branch of math.
If logic is a branch of math, then the correct answer is "no."
Branching doesn't work both ways.
