Be on your best behaviour; be careful of your language
Economics: P= Price and Q = Quantity Demanded.
The p in PS means post script and you write it afer leters for things you forget. If you are referring to the old expression, "mind your p's and q's" it stands for pints.
Well, they stand for nothing. They're just a metaphor.
Barkeepers used to keep track of what a drinker consumed by pints and quarts thus the p and q. Mind your p's and q's simply meant drink only what you paid for.
(p+150) + q = 1000 p+q= 1000-150 =850 Value of q is 425 and value of p 425 plus 150 ie. 575
It is an expression to "mind your behavior".

Converse: If p r then p q and q rContrapositive: If not p r then not (p q and q r) = If not p r then not p q or not q r Inverse: If not p q and q r then not p r = If not p q or not q r then not p r
The sum of p and q means (p+q). The difference of p and q means (p-q).
Not sure I can do a table here but: P True, Q True then P -> Q True P True, Q False then P -> Q False P False, Q True then P -> Q True P False, Q False then P -> Q True It is the same as not(P) OR Q
q + p
If p = 50 of q then q is 2% of p.
