Your 3 * 7 and 3 * 5 got interpreted as a highlighting of the text surrounded by the asterisks. You can edit your comment to fix it. Here are the complete HN markup rules: Blank lines separate paragraphs. Text surrounded by asterisks is italicized, if the character after the first asterisk isn't whitespace. Text after a blank line that is indented by two or more spaces is reproduced verbatim. (This is intended for code.) Urls become links, except in the text field of a submission.
