Let A, B denote arithmetic progressions with initial terms equal to 0. The union of A, B is sequence U, containing all elements of A, B without repetitions. We will derive the formula for the n-th element of the union U(A,B)=(u_n) in the form: u_n=f(n,a,b). The continuations of this paper are available in: http://vixra.org/author/waldemar_zielinski

Several infinite products are studied along with their finite counterparts. For certain values of the parameters these infinite products reduce to modular forms. The finite product formulas give an elementary proof of a particular modular transformation.

Some examples are given of very counterintuitive results from betting on a tossed fair coin. Various betting schemes are examined and a preliminary partial classification scheme produced. A call is made for more research with a list of things that are needed.
