Math tricks
By: Reynold Conger
This is a secret used by the engineering community. After all, accuracy is vital to good engineering. Thus all engineers check and double check their calculations. In these days of calculators, it is especially necessary to check answers. It is all to easy to press...
 Statistics & lies: Assessing the value of collected data By: Arthur Penrose It has been said that there are three kinds of lies: lies, damned lies, and statistics. The quote is often attributed to Mark Twain, but in fact he was quoting British Prime Minister Benjamin Disraeli. "Figures often beguile me," wrote Twain, "particularly when I...
Division by zero is it really Impossible
By: G E Barr
ACCORDING TO THE RULES OF INTEGERSBecause anything right on the number line is greater than anything left, then zero has a value greater than any negative integer. Because zero has a greater value than what is left of it, on the number line, then division...
Maths zero and other Abstract Numbers
By: Charlotte Rouse
This question really highlights the true science of mathematics. Yes, it is very useful- we can calculate practical real-life problems such as how much a bag of apples costs, or even the distance from the earth to the moon. But it also requires us to...
Independent and dependent statistical variables
By: Mark Cowan
Independent and Dependent Variables in StatisticsIndependent and/or dependent variables occur in almost any situation in which statistics is used.It is important that any professional, whose field requires the use of statistics, understands the difference between independent and dependent statistical variables. Being able to distinguish...

Abstract algebra is a branch of mathematics which builds upon set theory. A set is a collection of elements in which order is unimportant. Set theorists also consider the nature of the elements in the set irrelevant; the rules governing set operations are the same...
Division by zero is it really Impossible
By: Roy Malton
In the case of mathematics, a number cannot be divided by zero. If you divide by zero, then you are not dividing at all. The operation of division is struck null when dividing by zero because by its very nature, it has no value. For...
