From the post: """It’s always bothered me that you can simplify “Simplify, simplify, simplify”"""
No, you can't really. You can just say "simplify" but it does not convey the same message.
That is, it conveys a suggestion to simplify (the first part) but it doesn't convey that simplification has so extreme importance that it's worth to repeat the message (the second part).
If you have to be a pedant and tell people to use a multiplication symbol, then use a multiplication symbol. The symbol is × (×), not the letter X.
If you want to be a better pedant, you better start paying attention, like for example to the fact that I alluded to x not being the multiplication symbol by a) putting it in quotes and b) writing ~ "x", where ~ is the well known "approximately equal to" math symbol.
