PlayStation 4, Xbox One, and Nintendo Switch are the major consoles of 2017. Among 100 game entries from the 2017’s top 100 chart, you want to find the number of games that are designed to work on consoles other than the popular three (i.e., PS4, XOne, and NS).

=COUNTIFS(XXXXXXXX"=2017")

=COUNTIFS( [ Select ] "=2017")

COUNTIFS tests multiple criteria simultaneously (logical AND). To count 2017 entries whose console is not PS4, not XOne, and not NS, you must provide one criteria pair for each exclusion plus the year criterion. 1) Relevant knowledge points and concepts - COUNTIFS(range1, criteria1, range2, criteria2, ...) returns the count of rows that meet all criteria (AND). - To exclude a value use the "<>value" operator (not equal). - Each criteria_range must be the same size (e.g., D2:D1301 and A2:A1301). 2) Step-by-step reasoning - The console column is in D (D2:D1301). We need three exclusions: <>PS4, <>XOne, <>NS. COUNTIFS cannot accept a single criteria that means “not any of these three,” so we supply three separate criteria on the same range: D2:D1301,"<>PS4", D2:D1301,"<>XOne", D2:D1301,"<>NS". - The year column is in A (A2:A1301). We add A2:A1301,"=2017" as the final criterion. - Putting the pieces together in the required COUNTIFS argument order yields: D2:D1301,"<>PS4",D2:D1301,"<>XOne",D2:D1301,"<>NS",A2:A1301,"=2017" 3) Intermediate/formatting details - Ensure each range spans the same rows: D2:D1301 and A2:A1301. - The full formula would be: =COUNTIFS(D2:D1301,"<>PS4",D2:D1301,"<>XOne",D2:D1301,"<>NS",A2:A1301,"=2017") 4) Why this is correct - COUNTIFS applies all criteria as AND conditions: a row is counted only if its console is not PS4, not XOne, not NS, and its year equals 2017. That exactly matches “designed to work on consoles other than the popular three” for 2017 entries. 5) Why other approaches are incorrect - Using a single "<>PS4" alone would still count XOne and NS entries (not excluded). - Trying to use an OR-style criterion inside COUNTIFS (e.g., "<>PS4|<>XOne") is invalid syntax. - Using SUM of separate COUNTIFs could double-count rows unless carefully structured. Conclusion: The correct COUNTIFS argument sequence is D2:D1301,"<>PS4",D2:D1301,"<>XOne",D2:D1301,"<>NS",A2:A1301, which matches the provided answer.
