nit: I hate trying to work out what "10x fewer" or "10x less" mean.

Let's say I have a counter value, X = 100. I reduce that to 10. How can I phrase that in English?

"Value reduced to 10% of original value"

"Value reduced by 90%“

"New value is one tenth the original Value"

Using multiplication with a positive integer and saying "less" just seems incomprehensible when it flies by during a sentence and I can't stop myself from mentally saying "No", like Neo at the end of the Matrix when the three agents fire a volley of bullets at him down the corridor. "No, this sentence stops right here while I pick it apart"

I don't understand how you can build up this sort of reaction but you still need to "work out" what it means. It sounds like you learned what it means just fine.

Also the most direct translation is "value reduced by a factor of ten".

"x" means factor, "fewer" or "less" means reduced.

"10 times less" contracted to "10x less" maybe?

The first sentence seems fine to me. The contraction much less so.

Sorry, only seeing this now. But this is precisely what I mean. What would 1 times less mean? 0? It's just an awkward way to phrase something that can be said much simpler using a fraction or a percentage.

“Value 10x less now”

Sounds good as non-native.
