The function has returned the sum of 3 different ranges: A8:A12, B8:B12 and C8:C12.
 
4th Example:-

In this example, we will see what happens when our range contains any logical value.

Follow the steps given below:-

  • Enter the function in cell D14
  • =SUM(D8:D12), Press Enter

The function has returned 16 values. It means SUM function ignores any text value which is comes within specified range.
 
5th Example:-

In this example, we will see what happens when we enter error value in the range for which we want to calculate sum.

Follow the steps given below:-

  • Enter the function in cell E14
  • =SUM(E8:E12), Press Enter

It returns #N/A error only. Because, the function does not allow any error value in the range and hence it returns an error.

So, this is how SUM function works in different situations.
