What are topological quantum field theories and their invariants defined by summations?

Jun 6, 2023 ... 'Sum' calculation is the total of all criteria together. 'Mean' calculation takes things one step further by dividing the total by the number of criteria. Summation is a shorthand way for writing long additions. Explanation: Say you want to add all numbers up to and including 50. Then you could write out: 1+2+3+... ... SUM function · =SUM(A2:A10) Adds the values in cells A2:10. · =SUM(A2:A10, C2:C10) Adds the values in cells A2:10, as well as cells C2:C10. Nov 9, 2011 ... 1.
