There is no need for an abbreviation to represent the letter r since it is only one letter long, and is not a particularly difficult character to write.
Conversely, the letter r is used as an abbreviation to represent a number of different concepts/measures, some of which follow:
r = radius, regression coefficient, radians, the second parameter in permutations and combinations.

What is correct math or math?
Right…MathematicsMaths = correctMath = incorrectMath. (with a full-stop) = correctOnly Math. Is correct because the last letter of the abbreviation is NOT the last letter of the abbreviated word (Mathematics).Maths doesn't need a full-stop and is correct per se, because 'S' is the last letter of 'Mathematics'.Math. Needs a full-stop because 'H' isn't the last letter of 'Mathematics'.However this is British English, it's typical of American English-users to ignore this rule, hence why Mr. and Mrs. Is used in America, as opposed to Mr and Mrs as used in the UK.MisterMissesMr ('R' = last letter of 'mister' = no full-stop needed)Mrs ('S' = last letter of 'misses' = no full-stop needed)NB: if you are American, a full-stop is the British term for a (grammatical!) 'Period'.Hope this helps someone...CommentTwo points. First of all, 'Mrs' is the abbreviation for 'mistress', not 'misses'! Secondly, it seems to me that as 'mathematics' is plural, it would make more sense to say 'maths', rather than 'math'.
