FRS is evidently inundating the shareware world with educational software. This is commendable, but the idea (for one example) of distributing "Division Drills" and "Fraction Calc" as separate apps for which separate shareware fees should be paid is ludicrous. Neither app could take a reasonably competent developer more than a day or two to whip together. Should you pay ten or fifteen bucks for such an effort? Somebody may shortly give you the same capabilities more inexpensively or even for free. You decide. The summer is young. Caveat emptor.
