The most difficult part of the passage for me was the
wording in expressing the biconditional.
I feel as though if and only if and also sufficient and necessary seem
almost redundant. The end of the reading
tried to justify it, but the explanation was extremely wordy.
The most interesting section, I found to be the reasoning
behind the symbol with the three lines or equivalency. I remember using that symbol a lot especially
in chemistry and other math courses and had always assumed it to mean the = sign
but just fancier. Now I understand the
meaning as if one is true, then so is the other and likewise if one is false.
