Does order matter in nested quantifiers?
Nested Quantifiers
When we have one quantifier inside another, we need to be a little careful. The first is true: if you pick any \(x\), I can find a \(y\) that makes \(x+y=0\) true. ... So the order of the quantifiers must matter, at least sometimes.
Does quantifier order matter?
When quantifiers are of different types, their order matters. Follow this rule: when order matters, the first quantifier quantifies the subject of the sentence; the others quantify the objects of the verb. For example, let our universe of discourse be human beings, and let Lxy mean x loves y.
