For each of the following relations on the set of all integers,
determine whether the relation is reflexive, symmetric, and/or
transitive:
(?, ?) ∈ ? if and only if ? < ?.
(?, ?) ∈ ? if and only ?? ≥ 1.
(?, ?) ∈ ? if and only ? = −?.
(?, ?) ∈ ? if and only ? = |?|.

In the following determine whether the systems described are
groups. If they are not, point out which of the group axioms fail
to hold.
(a) G = set of all integers, a· b = a - b.

product of integers.
(c) G = a0 , a 1 , ... , a6 where ai · a i = ai + i if i + j

Using nested loops, write a function called primes(a,b) that
takes in two positive integers a and b (where a<b). Then simply
RETURNS a string containing all the prime numbers between a and b
(or if there are none, the string "No Primes"). You should check
that a and b are valid inputs, that is, that a and b are integers
such that a<b (otherwise, the function should print “No
Primes”). Three sample calls of your function (in IDLE) should
produce...

ex. C = |x|(xy/xy) C = xy/|x|
ex. P x --> y = Cux = C(xy/x) (1/|x|) (x) =( xy/yy)(y)
