If there is only one being used, though, we read it as A regardless to the font. This is a soft question. We can read the letters , , etc. as bold A, bold B, etc. We can read the letters AA, BB, etc. as italic A, italic B, etc. We can read the letters , , etc. as calligraphic A, calligraphic B, etc. But how do we read letters such as , , etc., or , , etc.? 5 I think ,, reads Blackboard bold A, Blackboard bold B and , reads Fraktur A, Fraktur B. – Hanul Jeon Jan 22, 2013 at 13:23 10 I usually just pronounce them as , etc. Its rare to speak matematics without any support of written text, either in a book or on a blackboard, so it rarely causes any misunderstandings. – mrf Jan 22, 2013 at 13:23 I would say blackboard bold A or script A, respectively. – Clayton Jan 22, 2013 at 13:24 1 Considering the TeX language, I usually speak bb A or cal A or frak A, since we use \mathbb, \mathcal or \mathfrak. – Sigur Jan 22, 2013 at 13:35 1 Clayton (and others who suggested script for Gothic): How would you read ? – Asaf Karagila Jan 22, 2013 at 13:36 1 AsafKaragila: Exactly the same, actually. I tend not to get hung up on specifics. If the notation calls for it, I would use , , etc. as opposed to using the same letter in different fonts for multiple meanings. – Clayton Jan 23, 2013 at 0:37 I think it is just acceptable to say A and B...
It is quite rare that you have to read out aloud any maths that has the same letter appearing in two different fonts like this. Please read out loud the following sentence: – Asaf Karagila Jan 22, 2013 at 13:46 12 Small pee is an element of pee which is a subset of the powerset of A? – Willie Wong Jan 22, 2013 at 13:54 2 If I were teaching a class, Id read that as let p be a subset of A chosen in the family big p (or something similar according to context) – Andrea Mori Jan 22, 2013 at 14:35 Yes but how often does such a sentence come up in everyday maths? Also usually there is a bit of context which allows you to get round having to read it exactly as it is written...for example our subset of – fretty Jan 24, 2013 at 9:59 参考
