I think Math Solver should be able to produce an equation by writing its name. Like if I said "compound interest" it would give the equation. It should also be able to apply that named equation. So, if I said, "the compound interest of some amount at some percentage, etc" it would be able to calculate this. I guess word problems in general. You would be able to hover over the sentence with the S Pen and "solve" would be an option.
