I just want to make sure I'm understanding the %s and #s correctly.
Some...not means there exists 0-99% of the two ideas. Some dogs are not friendly means 0-99% of dogs are friendly. 1-100% of dogs are not friendly. there exists at least one dog which is not friendly. Whereas saying all dogs are friendly would mean that 0 dogs are not friendly. 100% of dogs are friendly.
Original statement: Some alphabets are not phonetic.
Lawgic: A (--s--) /P
% meaning: 1-100% of alphabets are not phonetic. 0-99% of alphabets are phonetic.
Number meaning: there exists at least one alphabet which is not phonetic (A & /P)
Negation: A --->P
All alphabets are phonetic.
100% of alphabets are phonetic.
0 alphabets are not phonetic.

This is in my understanding correct. It helps to know these negations both ways: be able to negate the all statement into the "some are not" and also be able to negate the "some are not" into an all statement. A really good example of how important it is to have mastery over this concept is PT 54-2-9.
