Before you get your mind drowning deep into that gutter water, I'm not talking about that kind of adult language.
What I want to say is that when you work for a company that has some semblance of professionalism, the least you can do is try to use professional-sounding language.
I won't go into details, but if you're a grown person, it's NOT okay to say "timsing" when you mean "multiplying" in your letter. In fact, it's not even okay once you've passed grade 3 (or whichever grade it is when they start teaching multiplication).
