Every American dreams of hitting the big time. The national and state lotteries in the USA, are exactly the kind of instant gratification that personifies the American public. While there are no "sure fire" ways to win the lottery, it is important to know how you can sway the odds in your favor even modestly. If you dream of lavish mansions, and private chefs, or even if you are only a casual lottery player, this article is a must read.

Binary numbers, as it is known, are mainly involved with going with just two digits being a 1 and a 0. For this purpose, it is going to be focused specifically on being able to add the numbers together. Believe it or not, it is not an extremely difficult task, though it can some take some serious practice.

Binary numbers tend to focus on either being a one or a zero. For Mathematical purposes, the focus is going to be primarily on how to convert a normal number into a binary number and can range from either being a really small or really large number. The process is not too difficult but will take practice.

Knowing how to divide fractions can be helpful when going to be working with them directly. It is not too difficult in terms of understanding how it works but can be challenging if not patient enough. There isn’t much in the way of requirements and some tips. Doing it with smaller numbers will make the transition to larger numbers much easier because of having the basics down to a science.

Calculation of real eigenvalues of a square matrix is often required in physical problems. In most of the cases it is not possible to find the eigenvalues by hand and we need to use numerical methods. In this article I have discussed one such method with a C program involving finding determinant of a matrix by the method of Gaussian elimination and determining roots of an equation using the method of bisection.

Series expansions of the inverse trigonometric functions are often required in physics and mathematics. In this article I have described a novel method of finding the expansions using the knowledge of derivative, integration and binomial expansion. This method cleverly avoids the cumbersome method Taylor expansion, involving higher order derivatives of those inverse trigonometric functions which are very difficult to calculate.

The calculation of exact functional values of Riemann Zeta functions, zeta(n), require complicated calculations or numeric, but they can easily be approximated by doing mere calculations by hand. In this article I have discussed a very simple method of approximating zeta functions and also provided a “C” code for a better approximation.

Puzzles have perplexed human mind for centuries. In this article I am going to talk about one such baffling puzzle on infinite exponentiation which will lead to a simple non-linear equation. During the course of solving we will learn how to analyze stability of a solution of an algebraic equation. This will reveal one application of non-linear dynamics on simple mathematical problems.

This article describes how to convert a decimal number into a negative base with a number of illustrations. The process involves four steps: 1. Convert the decimal number into the base b, 2. Break up the number in even and odd parts 3. Convert the odd part into negative base 4. Add the converted parts to obtain final answer

Finding area of an ellipse is a very cumbersome task using conventional calculus but using some trick that can be done very easily. In this article I have shown how to do that. The method makes use of the natural length scale inherent in the physical problem. Application of the same method is used to determine the volume of an ellipsoid.

This articles is about chi square testing and what steps are used to determine the value of the chi square testing. Also, this article is about understanding degrees of freedom/probability values and how it relates back to chi square testing. This article gives readers a step by step approach in finding the chi-square value and the probability value using the chi-square value.
