: 1. which integers leave a remainder of 1 when divided by 3, a remainder of 3
: when divided by 4, and a remainder of 4 when divided by 7 ?
: +
: 2. suppose that f:Z -> R with f(1) = 7, and f(n)=4f(n/3)+7, for n=3^k,
: +
: k屬於 Z . Solve for f(n) relative to the set S = { 3^k l k屬於N }.
: 3. Let F(x), P(x), and M(x,y) be the statement "x is female,""x is a parent,"
: "x is the mother of y," respectively. The statement "if a person is female
: and is a parent, then this person is someone's mother" can be expressed as
: a logical expression involving predicates, quantifiers with a universe of
