Some of your formulas in MathJax are too long - we cannot see some part of them. Try to use \\ to separate your formula into lines, so that we can see the full formulas.

By the way, if you want to write subscripts of subscripts, you must use things like a_{b_c}, not a_b_c. Also, a_bc will be treated as a_{b}c - c is not in the subscript.
