Question
Hi , hope you can handle this subject ,or can find someone.

My question;
Analyze the following : P impliments ( Q + R)

In math ; P --> (Q + R)

A:is this a valid Propositional calculus expression ?
or
B:is this a valid Predicate calculus expression ?
or
Both

according to the text Propositional calculus is ALL uppercase and they use the end of the alpabet.
then Predicate calculus uses lowercase , tho the first position must be a letter.
Tho the symbol " + " is not listed as a symbol to use in either one .

Thank you , jerry  

Answer
i "BELIEVE" the answer is A.) Info found at http://www.uea.ac.uk/~j108/propcalculus.htm

its the only site where i find your problem and propositional together.

by the way & is just another way of saying + since you are putting 2 things together.
