Hi
Please tell me if tensor algebra is neccesary for understanding GR.
I dont know anything about tensor algebra.

Thanks in anticipation

Yes. In fact you'll need tensor calculus. Many GR books introduce the necessary math. See some of the threads about GR books for pointers.

In their book Exploring Black Holes, Taylor & Wheeler work out some of the physics of black holes by starting with the Schwartzschild metric as a fait accompli, so they don't have to introduce tensor calculus. (The derivation is done in almost any book on GR and does require an understanding of tensor calculus.) I think they assume a knowledge of SR, though; their discussion of SR is pretty brief. So you may want to work through their book Spacetime Physics first.
