[pzzldstudent]

I've used Cramster to create my question in detail since it has the mathematical symbols I needed.

Any advice, suggestions, ideas, and help is greatly appreciated.
Thank you very much!

Number 4 reads:
"for any(or all) real number(s) 'a', there exists a real number (not a single one) 'b' such that a+b=0."
Whatever 'a' is, you can pick out the 'b'
This is true.

I agree with the first three.

Statement 4 is the existence of negatives axiom I've always been taught:

"For every real number x there is a real number y such that x + y = 0."

Thanks to everyone who replied! It helped a lot!

I'm very new to this forum (just joined yesterday). Now how do I mark this forum as 'closed' or 'solved' so that people don't have to view it anymore since my question's been answered?
