When nesting one function inside another, it is not possible to open the second, or nested, function's formula builder to enter the necessary arguments. For example, below we have a birthdate in B1 and we want to calculate current age in B2: The YEARFRAC function will calculate years with a start date and end date: They would then be nested as comma-delimited arguments within the sum() function, creating a formula that looks like “=SUM(AVERAGE(A1:A15),AVERAGE(B1:B15))”. This sequence can also be inverted, where you average the sums of different columns by typing "=AVERAGE(SUM(A1:A15),SUM(B1:B15))". Many users set up long and complex formulas with fixed values typed directly into the formula.
