First, don' t use Set ( = ) in an equation; use Equal ( == ) Floor[Sqrt[19] + 7] 11 So the result is empty since Meter cannot be 11 and less than 6. If you meant the Sqrt to be negative Solve[Meter == Floor[-Sqrt[19] + 7] && Meter < 6, Meter] {{Meter -> 2}} Bob Hanlon ---- KenR <ramsey2879 at msn.com> wrote: ============= Solve[Meter = Floor[Sqrt[19]+7] && Meter < 6, Meter] gives a null "{}" Any workarounds?
