I have read Special Relativity from Resnick and Halliday's book Fundamentals of Physics. Now I want to read general relativity. I tried reading Einstein's book "Principles of Relativity", but sad to say, many things went tangentially above my head because I couldn't follow many equations, as they started almost without any context. It doesn't matter if the book has great lot of equations, because I can deal with them, but it should have a little bit of explanation as well. But I don't want a book that has only explanations and no equations or numerical practice problems. So, basically I want a book that has both explanations and numericals and equations. It may be of any level, like UG, PG and the like.
