Understanding different base number systems
By: Al Plante
Introduction This article explains the general meaning of number bases. Common base 10 numbers are used to lead into the generalized form of a number expressed in any base, b. Afterwards, the reader is given a walkthrough conversion to base 8 (octal), followed by a...

Is it possible to divide a number by zero? Conventional thinking in mathematics declares this to be impossible, but this answer is contingent on a point of view. The problem here lies in the normal interpretation of the value of the number zero; a representation...

Abstract Algebra has to do with systems of algebraic equations. Beginning Abstract Algebra is based on the book Euclid's Elements. The Euclidean Algorithm and Euclid's proof that the prime numbers are infinite are important. The Euclidean Algorithm is a method that finds the greatest common...
Division by zero is it really Impossible
By: Rick Scythe
Hello, I'm Zerodactyl. I believe that it is possible to divide by zero. The reason that it hasn't been proven is because people overlook all of their own concepts. There have been remarks such as that dividing one by each shrinking decimal makes the number...

When you are using figures to emphasise the strength of your business in a particular area, how do you display it in press material? For example, would you say 'nearly 300' because that takes the figure up to a significant milestone or would you say...

Abstract algebra, now commonly referred to as just "algebra," is a field in mathematics which concerns itself with algebraic structures such as rings, groups, fields, vector spaces, and algebras. These structures bear importance in mathematical physics; for example, quantum mechanics is often concerned with...

As a math teacher, I like to perform several math tricks for my students, as well as friends and family. Many common tricks are based on properties of integers, and order of operations. These are nice, but can become stale after awhile. I have an...

This is possibly the most commonly asked question by students to teachers in a mathematics lesson. It is a question that enables the minds of millions of students everyday. Following just basic laws and rules of mathematics, that any number divided by itself is one...

As a former math teacher I was faced with this at least once per class. So if you are a teacher there is an easy answer that brings the student back into focus. You can have that students calculator out doing real life math is...
