INDEX returns the cells specified by a row and column number. In the applied function, you can first transform the row into a boolean array using between method or with standard relational operators, and then count the True values of the boolean array with sum method. The problem: You have a list of numbers, some of which sum up to another number. The sum of two numbers is 12.
