I feel like it could be better shown, for a variety of examples, how formulas can be used. For example, this image doesn't really tell you what the answer to the example is. The example only shows that those data types can be used but doesn't help you understand what it does. Minor gripe I suppose. Also sometimes I wonder if I can use an array input or only a single value into some formulas (because in Excel this is commonly possible), but it seems "matrix" math type formulas aren't really supported here. Nevertheless, I feel like being more detailed about data types, showing the results of the example, and possibly giving some examples of advanced use-cases would be a great improvement.
Thoughts?
