Use factorization.

40 = 8*5

so (g-8 )(g+5) = 0

=> g = -5 or 8

We do that ,too (in Germany). Only problem is: Some algorythms of the calculator that we HAVE to use are buggy as hell- for example it should multiply/add vectors for us and the tasks in our end-of-highschool tests will be very hard to do without a calculator. Unfortunately our calculator refuses to work with    3d- vectors that have a 0 or a 0.x in their last variable :roll:
