Well, not exactly mathematical - you just hear it, and there's many ways to learn it. I've (literally) seen people using their motoric memory by playing along on an imaginary instrument and writing things down when they "got" it right. Others (good sight-readers) just read what they've written and play it back in their head to listen if it's right. Some people have perfect pitch, others don't but are perfect in recognizing any interval. I tend to recognize which note in a scale is played (so I need to remember the base note of a tune/key, if applicable) and measure the distance by counting half and full tone steps up or down (a crutch, actually, but it works). We did this at school, and I had most problems with 12-tone listening exercises with not tonal reference point. I really like the diatonic character of ITM, this makes getting tunes down rather easy
My point: there are many ways to analyze what you hear to the point of writing it down, or playing it without too much note-hunting on an instrument, and it is a skill that can be learned, whatever method works for the person in question. I always "have" the rhythm and some sort of drone as a reference, but I don't hear intervals too well. The note-hunting approach doesn't work for me, as I immediately forget the rest of the tune when I get one note wrong. That's why I sing first.
This analysis, however, is the second step after remembering the sequence of notes I want to play, or write down. I have to remember the part long enough to listen to it mentally, and this is really hard at most normal-speed traditional recordings. What is crystal (Crystal?) clear in listening goes "poof" when it comes to just singing, so I'd encourage any beginner to not give up at this stage. Sometimes, the only way is to listen as long as I can stand it, and then put it away and wait until the tune comes back to me when I don't expect it.
