There is no certainty in math. But when you encounter conflicting claims

 Well, that's exactly the opposite :)
There is nothing but certainties in math, since everything is proved in a non-discutable way.

Not really.. for instance, there are people who reject proofs by contradiction, so some proofs might be acceptable to some while being rejected by others.
Also, things that used to be considered obviously true, like the shortest distance between two points being a straight line have later become uncertain (with the potential curvature of geometry as opposed to flat geometry).
And there is evidence that we can't even have a completely reliable system where we can prove everything that is true and nothing that is false, since Gödel has shown that any formal system that includes basic arithmetic must necessarily be incomplete.

And there are open problems and conjectures, that are not been proven yet. But of course nothing at the low student level of the poor dumb french man.
