(00:50 min) SUMPRODUCT can be used to house a single array calculation when you need to add the result of the array calculation (Array Operation without Ctrl Shift Enter). 2. (01:23 min) Formula goal: single cell formula to calculate rounded total sales given units column and price per unit column. 3. (02:10 min) Calculation of: =SUMPRODUCT(ROUND(B6:B10*C6:C10,2)) 4. (03:53 min) Multiply arrays with same dimensions and then add. 5. (04:53 min) SUMPRODUCT treats array entries that are not numeric as if they were zeros. 6. (06:04 min) If you are multiplying arrays that are not the same dimension, you can use the multiplication operator *, but watch out for text entries. 7. (08:19 min) Excel 2003 and earlier, SUMPRODUCT great for counting and adding with more than one criteria. 8. (08:19 min) The array argument in the SUMPRODUCT function is programmed to perform array calculations without the keystroke Ctrl + Shift + Enter. 9. (13:26 min) Calculation of =SUMPRODUCT(--(B62:B68=F62),--(C62:C68=G62),D62:D68). (15:09 min) Timing Different Formulas with Charles Williams VBA timing code. 10. (19:08 min) Don't overuse the SUMPRODUCT function, when other functions may be more efficient (may require timing).. 11.

(29:38 min) Formula to count with year & month criteria that is mismatched against serial number data (3 examples). (40:45 min) Timing for 3 examples. 20. (41:45 min) Selecting most efficient functions for Array Formula can reduced calculation time (may require timing). 21. (42:22 min) IF Function's requirement to use Ctrl + Shift + Enter trumps other functions requirement to NOT use Ctrl + Shift + Enter, ALWAYS.
