Is Math needed for Back-End

Hello Guys hope you’re having a good time in this quarantine. I’m learning Front-End development (I’ve learned Html, Css and now I’m Learning JS (a course from Udemy).And I plan to Learn JS and React by the end of this year and after that I think to go Learn Back end.And one of my question is do I need to be good at math to learn Back-end?
Thank you , have a good time and stay healthy.

I’m assuming you mean some specific mathematical subject like college-level calculus, statistics, linear algebra etc (rather than basic maths that is used everywhere)

If by “back end” you mean writing the server side of web apps, then often no. If by “back end” you mean anything that isn’t client-side web development, then that covers a vast number of areas, so it completely depends on which area.
