If you work an office job more than likely you will be writing memorandums (The definition of a memorandum is a note or reminder left for yourself, or a form of communication designed to share information.). A memorandum is quite easy to put together. At its most basic form memorandums, or memos for short, are just a short form of a letter. There may be a heading written in bold or italics for emphasis. Additionally, the memo may address a certain issue or request permission to do something from an upper level executive.
