Error and Mistake

意思接近，以下引用 oxford 出版 word for word (2003) 中 mistake 條解釋（譯本）：
error：常指與計算有關的錯誤，或指誤解／錯誤判斷；error 比mistake 較為 formal
e.g. There must be an error somewhere on this bill. It is much too high.
mistake：行為或判斷的錯誤，或受誤導而犯的錯誤
e.g. We made a mistake in buying that second-hand car.

error 一定係noun,
而mistake可以係noun 或者係verb

不過意思上差唔多
