This is the first video in a series on solutions to the Formula Challenge to find the first sales transaction for each month of the year. There were over 100 solutions submitted on the blog page, so I created a series of videos to explain the most popular solutions.

The most popular solution was to use a MIN IF array formula. This first video explains how array formulas work with a simple example.

I also explain how to enter the array formula with Ctrl+Shift+Enter. We then use the Evaluate Formula window to step through each part of the formula and learn how Excel calculates arrays.

In the next video I explain how to combine the MIN IF with VLOOKUP or INDEX MATCH functions, to return a matching result from another column.

We will also look at NON-array solutions withe AGGREGATE and MINIFS functions in future videos.
