Modify the following four Memo according to the URL links I gave. In addition, a memo has a set of different formatting requirements from an email and a business letter. specifically, a memo has a title, such as “MEMORANDUM” or “Memo”, at the top of the page. Moreover, after the title, a memo includes four lines of information, including the recipient, the sender, the date, and the subject line. Most often, official titles of the recipient and the sender are included next to their names. Thirdly, unlike an email or a letter, a memo does not have a greeting at the beginning or a valediction at the end of the message. To modify the method, please visit https://www.youtube.com/watch?v=m7tmsWN6uH0, one of which is a pdf file, and I hope you can modify it into a word document.
