Summer of Math Exposition

I feel like this article misses some context.

Missing quite a lot of context. You have to "show", not only tell. The content is good but you need to be more cohesive in presenting it. For example, you could give a definition and example of an Euler sum, the "powers conjecture". It might not be your cup of tea but it might also be fun to provide some story behind the mathematics! It helps build a story and it can help with engagement.

It goes a little fast - a bit more explanation on the reasoning would help

Not much motivation... a lack of clarity that bordered on numerology. Be more verbose! Start more at the beginning.

Dear Math Diary Writer, I very much enjoyed reading through your journal entry because of the enthusiasm and animation of wandering into the unknown and the sheer play for numbers. This entry further emphasized the beauty, broadness and delight math evokes for its inquirer. I'd like to point out in terms of exposition, it might need some body of structure that elaborates a bit more on some topics within number theory. In short, perhaps these math diary entries may serve as a building block for you to expound upon the hidden math gems you've successfully found!
