Can you recommend textbooks on higher mathematics in order to quickly refresh your knowledge for studying computational mathematics (numerical methods)?

Question

higher mathematics

Good afternoon!
Advise, please, not abstruse textbooks / reference books / etc. sources of information in order to refresh knowledge in higher mathematics. Now I started studying computational mathematics and I need to remember some points. I downloaded several books, but either a very dry language, or an abundance of formulas with little or no explanation, or few examples. Since there is a full-fledged study (software engineering, remotely), there is simply no time to download, start a book, and then look for a new one again. Maybe someone already has a good selection? Thanks in advance.
