@Math_files I have really made this mistake before. Dont ever ignore unit. It's important in any case. It may seems irrelevant when u simply add or minus, but if u multiply u will understand how much it matters.
@greatestptl once, a guy from our country did sth really sucks, in his apology announcement wrote "i'm a son of a bitch", and people from other countries were like: "it's ur fault, why call ur mom a bitch?" 😂😂🤣
