Does the subject want to ask, "A word formula is not a word, but is it?" No. According to the public information related to the query, the formula in the formula editor appears in the form of pictures, which is not a word, so it is not counted when checking for duplicates. When Word documents count the number of words in a paper, spaces will not be counted in the total number of words, but only the actual number of characters will be calculated. The paper duplication checking system will count spaces into the total number of words when detecting the repetition rate of papers.
