In English, x or time(s) after a number marks a "unit" used by various verbs. A 10x increase. Increase by 10x. Go up 10x. Some of these verbs are negative like decrease or save. "Save 10x" is the same as "divide by 10". Four times less, 5 times smaller etc. are long attested.

Agree to disagree.

It's basically multiplication with fractions, just like you get 1/4 from 1/2 * 1/2, which is once again a multiplication that turns into division

I agree that it's a suboptimal and click baity way to phrase it though...

		Exactly, it's multiplication. Example: He was saving $10 every month before the change. Then he switched and now he is saving 10 x $10, ie $100 every month. But that's not the case here, right? And that's why the parent post is correct.

No, x literally means multiply. It doesn't somehow also mean divide. They should use the percent sign, it's what it is for. 10x my costs means 10 x mycost, it's literally an equation

It's just inversion, like 2 to the power of 2 or 2 to the power of negative 2. These negative words inverse it just the same. You may dislike it, but millions of people have spoken this way for a long time.

> x literally means multiply

And some use the dot operator or even 2(3) or (2)(3). When programming, we tend to use *.

		Nobody says times to mean divide. The word "negative" is what is doing the inversion for you in your example.

Thats not how English works.

Saved 10x would imply there was an amount being saved that they multipled.
