Difference between rational and irrational numbers
By: Steven Mars
Rational numbers can be expressed as the ratio of two integers. Irrational numbers are the opposite—they cannot be expressed as the ratio of two integers. Rational numbers and irrational numbers are called the real numbers. The complex numbers are the real numbers plus the...

Is Division by zero possible
By: Steven Mars
Division by zero is possible, especially 0/0 because 0*0=0 and 00=0 (Explained further in next paragraph), which appears to prove that 0/0=0. However, the fact that 0*x where x is any number also equals zero appears to violate the laws of mathematics. Many years ago...

It would not be at all unusual for an individual to believe that there exist only two kinds of meaningful propositions. First, there are those propositions (or assertions) that are demonstrably true or false. An example of one of these is the proposition that...
How to study and understand mathematics
By: Chu Chin Kwok
How to study and understand Mathematics? Everyone has some notion of what mathematics is. A layperson who is not much exposed to math would say math is just numbers, shapes, and some simple arithmetic. To a serious student of math, math encompasses much more than...
Division by zero is it really Impossible
By: Bobby Brown
Technically, division by zero is "undefined", not impossible. In other words, no one has offered an (acceptable) definition for the possibility. As a result, for most quantitative purposes division by zero is prohibited. Calculators and math gods alike run into this foreboding barrier. What...

Integers are whole numbers that run from negative infinity to positive infinity, including 0. Adding and subtracting integers is a basic component of math, and this article will explain how to do so. >>> Adding Integers <<< The process of adding...
Biography: Christian Goldbach
By: Steven Mars
Christian Goldbach is a mathematician famous for a conjecture in number theory named after him (Goldbach Conjecture). It claims that any even integer greater than two can be expressed as the sum of two prime numbers. There was a million dollar prize a few years...

Probability is a precise way of describing what may happen. As a branch of mathematics, it investigates the likelihood of complex events, and the way complicated systems work. Looked at another way, probability is also used to describe our degree of belief that something will...

For many, the square root is one of the first mathematical concepts they will learn outside of simple addition, subtraction, multiplication, and division. The square root is a concept that not only combines multiplication and division, but also is used extensively in complex formulas...

In math, probability is the study of the likelihood of an event occurring. If you flip a coin, what is the probability that the coin will land on heads? Probability of this event occurring is expressed either as a fraction or a decimal from 0...
