what does "use moment" mean? "In real life scenarios like bidding, voting, and investing, you can sometimes use moments when a person's actions or claims change in response to hearing information to learn a lot about what they must have or know themselves." in this phrase, what does "use moments" mean? Is "moment" even a thing usable?

"But seeing as it's lunch time, you can get me a burger." Is 'as' here same with 'because'? Can I see this sentence as "But seeing because it's lunch time, you can get me a burger"?

Why there is no s here? "While a lot of mathematical notation has probably been forced on you in the past, even when it didn't seem useful (or when it seemed like an active hindrance), don't give up on notation or on drawing out your ideas!" Since we can count mathematical notations, shouldn't it be like "While a lot of mathematical notations have"? What's the difference between "a lot of mathematical notation" and "a lot of mathematical notations"?

Can I use "don't be fooled by something" to a person in a high position? The word, fool, felt somewhat rude to use without much thought, or so I thought.

help me with make a sentence. I heard "Would you tell it to Jim instead of Oliver?" means that the speaker wants them to tell it to Jim, not to Oliver. And if you put a comma after Jim, it could mean "The speaker wants them to tell it to Jim, because Oliver didn't want to tell it to Jim." But they said, it'd be a little bit grammatically poor. How do you make a sentence meaning "The speaker wants them to tell it to Jim, because Oliver didn't want to tell it to Jim."? Would it be perhaps.... "Would you tell it to Jim for Oliver?"

Would you tell it to Jim instead of Oliver? => meaning? Is this.... 1) The speaker wants them to tell it to Jim, not to Oliver. 2) The speaker wants them to tell it to Jim, because Oliver didn't want to tell it to Jim. 3) Could be both

I'm pretty hard [ to hear / of hearing] these days. What's the difference here? Or are they same? Thanks.

What do you need my help [ for / with ]? What's the difference??? Thanks.
