It's a shame that your own literacy is so limited, and that your own ability to parse the differences between words is disabled by a lack of vocabulary breadth. That's got to be frustrating. Or maybe not, since perhaps ignorance is bliss in some way, right?
Saying that something is "ten times smaller" is like saying "ten times more small." The phrase "ten times" is a multiplier. It means that you're describing an aspect of something, and saying that there is ten times as much of that aspect. In that usage, the aspect you're describing and comparing is the smallness.
By choosing that construction ("A is ten times smaller than B"), you're deliberately focusing on B's size, and implying that the smallness of B is the thing that's being multiplied ... that B's smallness is important in what you're communicating, and that it's of note because A's size is even more so (small, that is). If we're not trying to convey B's smallness as part of the concept being communicated (perhaps B isn't really thought of as small at all, in the scheme of things), a different construction makes more sense. Makes for better communication: "A is tenth of B's size." We're still describing the relationship, but doing so without including words that suggest B's size is already considered small.
That you don't have the cognitive and communication skills to understand the difference, or that you DO, and prefer to have communication dumbed down and muddied, and require more back and forth to clarify what you mean, says a lot about you. Which is unfortunate. That you think you have to insult someone else in order to feel better about it is just kind of pathetic, really.
