Thanks to Vincent for bringing this anomaly to my attention. These two simple equations test the 17BII+'s Solver. Run the first one to initialize the intermediate variable "B":
A+B+C
L(B:A)+G(A)-C
Entering 2 for A, and solving for C, gets the expected answer of 4.
Entering 6 for C, and solving for A SHOULD result in 3, BUT the 17BII+ will return either "BAD GUESSES" or "OVERFLOW". My 19B and 19BII perform as expected.
