Hello! (:
First of all, don't listen to that twit, Jesse. There is no such thing as 'American English Language', it's just 'English Language', because the Brits were smart enough to actually create a language. Those Americans stole it. So get it right.
Secondly, maths is actually a word according to several dictionaries:
Maths: plural of maths
Noun:
Mathematics: "her mother was a maths teacher".
Synonyms:
mathematics - math
So yesh. (: And it's down to ones own prefrence on what they want to say. If people want to say 'maths' instead of 'mathematics' or 'math' then let them. Not all things that we say are actually grammatical 'words'. And just because it isn't in a certain dctionary, doesn't mean it can't be used. Like ginormous. >.<
Thirdly, I understand what you mean. (: I can not just use any pen to do work; I found using cheap biros so annoying and crappy. /:
Personally, I loved using papermate pens, specally their biros with the black outercasing. They can be bought in WHSmith or Staples as far as I know. (:

Those are the ones I really like using. They write so beautifully. (': Call me sad, ut a true writer woudl understand what I mean when referring to a great pen. (':
Hope this helped! (: I hope you find a pen you like! :D
Much love,
