Do not understand concept of Riemann geometry.

[Enrico Fermi]

Hello I do not fully grasp the concept of Riemann geometry.Please can you use mathematical descriptions but explain them because I am only a 10 year old but of course I know significantly the theories of dimensions. Thank you.

Riemannian geometry is a very advanced branch of mathematics. To grasp them, you need to know general topology, differential topology and linear algebra. So you should probably learn that first.
