Or maybe the parentheses make it easier for kids, and everyone else, to see which elements belong together. Based on the number of adults I've seen who are still unable to stop moaning about the parentheses, I suspect age has little to do with it.
I was mostly referring to the 4 closing parentheses in a row. I agree it's something difficult for everybody. I have the habit to open&close parentheses immediately, even when I write in word, but it's definitely something that the "normal" person doesn't do, let alone kids.

I suspect if you can learn to play Mancala in elementary school you can learn to manage counting up to at least 4 braces.
