How many daily math sums should primary kids do?

When DS was 6, he did around 100-200 mental arithmetic questions (depending on difficulty) everyday 5 days a week.

Why in mathematics do we diverge from typical grammar conventions, such as the comma. For instance, if I want to write \"Consider a nonlinear continuously differentiable strictly positive function, f.\" Then that is completely acceptable. In fact, it comes off as weird if I instead write \"Consider a nonlinear, continuously differentiable, and strictly positive function, f.\"https://omegle.onl/ https://xender.vip/
You can see this lack of commas adopted throughout major works, and I've always wondered why?
I've never been great at grammar, and when I write a manuscript with someone who is, they always catch me out on all sorts of technical details that I miss. I am getting better, but as I am writing this, I am getting more and more conscious about my writing. lol
Is the reason for this due to the international nature of mathematics? Did perhaps someone notice that Germans don't even use the space bar, so why not do away with commas? Did the accountants and actuaries among us coopt the commas for all those big numbers in their financial books?
Any insights from the community?
