One on the concepts students have the most trouble with is the concept of ratio and proportion. If you don't understand what a ratio is and can't see fractions as ratios you can't understand rate of change and you can't do calculus. Fractions are hardthey are ambiguousthey can represent division, ratios, classes of quotients ((4)^(1/3) makes sense in the reals but (4)^(2/6) doesn't). We have to keep teaching fractions and ratios. They prevade all of mathematics. ....just my opinion...
Note: I think that it was said of Ramanujan that every number was his friend.
