<prompt> Human: This might sound incredibly stupid, but somehow my calculations of bi-weekly gross pay dont add up to annual-gross pay.According to ADP calculator if my annual gross is 50k, my bi-weekly gross pay is 1923.08.If I take this number and multiply by 2, to get a monthly amount and multiply prev. number by 12 to get yearly, I only get 46152. Almost 4k short. Why ?  <response>: 41248. There are 52 weeks in a year.
