    Can someone please give a very simplified explanation of Riemann Summs

    I am taking calculus 1 online and the professor doesn't answer emails especially regarding how to do something. I have done okay (average score for the class) but just don't understand it. I know what Riemann Sums find (the area under the curve) but I am so confused on how to find it except...
