Key Differences

"Remainder" is a noun primarily used in the context of mathematics or in general scenarios when describing what is left of something after a part is removed or used. It might refer to the residual amount in division or the unsold portion of something in commercial terms. "Reminder", on the other hand, pertains to causing someone to remember or recollect an event, task, or detail. It generally implies an aid or prompt to memory.
In mathematical problems, particularly in division, the "remainder" is the amount left over after division when one number does not divide the other exactly. For instance, when you divide 13 by 5, the quotient is 2, but there is a "remainder" of 3. In contrast, a "reminder" might be a note or an alarm set on your phone to remember an upcoming appointment or task.
From a commercial viewpoint, if a bookstore orders a hundred copies of a book and sells eighty-five, the fifteen unsold copies represent the "remainder". This term can also apply to the residual of any product or item. Meanwhile, a "reminder" in this context could be a notification sent to customers about a pending payment or an upcoming sale.
In summary, while "remainder" denotes what is left from a whole after a part has been taken or used, "reminder" signifies a tool, method, or instance meant to jog or boost one's memory about something.
