How to add cells in Excel

Background and Problem Context:

I created this course to help teach learners how to use Excel to add up numbers without errors. The learner taking the course would be a beginner and know how to open excel and start a blank workbook. There are three items in this course. One is an explainer video that displays the problem in a fun manner, along with basic instructions for adding numbers to Excel, then how to use the Sum feature to add them up. There is additional course materials that walk the learner through the process in a step-by-step manner.

Results:

By the end of the course materials (video and course instructional materials), the learner should be able to use Excel to add up numbers without errors.
