Nancy, I can understand that, since braces aren't usually used that much. However, in Symbolic Logic, braces are used to show precedence. Anything in parentheses has the highest precedence (), followed by brackets [], and then braces {}. For instance: If [(p and q) <> (r or s)] is true then {[(p or q is false) and (r or s is true)] or [(p and q is true) and (r and s is false)]}. Happy Holidays! Dom Fontana –> Sent from NY via AP <–
