It shares the equation editor/solver of the 19B(II) with the exception of trigs and the alphanumeric keyboard. There are actually a few differences between the 17B and 19B solvers. One such difference is that the 19B solver allows you to include TVM functions in solver expressions  that is, functional descriptions of N, I%, PMT, PV, and FV in terms of the other quantities  and have the solver do all the work in calculating the appropriate values. The 17B solver does not include these functions. (Though, of course, it still has TVM as a standalone capability.) John
