Ancient Math

"Ancient" I know how to use it (pretty useful if you can mentally imagine the abacus. I've seen some pro kids multiply 4 digits by 4 digits in a few seconds )

Anyway, it was a fun level, although it was a little hard to reach the draggables (but I think some devices can even move it by dragging the sliders directly... lucky). The design was pretty good (although it would be better if you put stone blocks in the outside areas of the bricks, that's okay... I guess I'm just a critic), and it was great. Good job! This seems to have a chance to be featured (but I'm not @richardfu, so we'll see).
