Get "Collins Dictionary of Mathematics".

Good when you're away from a computer.

By the way, just out of curiousity:

You know how the backwards capital "E" is a symbol meaning "there exists........"?

Well....if I put a vertical or diagonal slash thru that symbol, can it mean
"There does not exist..............."?

I mean, is there a symbol for "there does NOT exist......."?
If I draw a slash thru a backwards capital "E"---will it be common sense/knowledge to assume that I'm just saying "There does NOT exist...."

Well, you see what I mean? Kinda...sorta??

[tex]\sum[/tex]?????

That is the greek symbol sigma, it means summation. Its just there as way to informe you how to right an equation. For example:

[tex]\sum_{n=1}^{10} n^2=1^2+2^2+3^2+4^2+5^2+6^2+7^2+8^2+9^2+10^2[/tex]

Do you see whats going on here?

(Sorry if thats not what you meant)

I imagine Bomba is going for [itex]\exists[/itex], which does in fact mean "there exists".

No, bomba is going for "there does not exist" and the way he describes the symbol is exactly correct in the standard usage. For more fun, also try E! (there exists a unique)
