Math Forum: Ask Dr. Math FAQ: Integers, Rational Numbers, Irrational Numbers
http://mathforum.org/dr.math/faq/faq.integers.html Competition: low
By real number we mean, loosely, a number that we can conceive of in this world, one with no square roots of negative numbers (such a number is called complex.) A real number is a number that is somewhere on a number line, so any number on a number line that isn't a rational number is irrational. Math FAQ.) Pi is an irrational number because it cannot be expressed as a ratio (fraction) of two integers: it has no exact decimal equivalent, although 3.1415926 is good enough for many applications

Why conspiracy theories and the Illuminati are not real

All I have to say is, stop telling people like me about this stuff! It's making us paranoid! I don't care whether it's true or not! For the past day or so, I've lost sleep because of an irrational fear of whether the Illuminati are real or not. The Illuminati were nothing but a political organization in 18th century Bavaria opposed to monarchism ("Illuminati" means "Enlightened," and they were a product of the Age of Enlightenment when people finally started questioning hereditary rule)

Fractional (Rational) Exponents
http://www.purplemath.com/modules/exponent5.htm Competition: low
Fractional exponents allow greater flexibility (you'll see this a lot in calculus), are often easier to write than the equivalent radical format, and permit you to do calculations that you couldn't before. Looking at the first examples, we can re-write them like this: You can enter fractional exponents on your calculator for evaluation, but you must remember to use parentheses

Also least absolute deviations requires iterative methods, while ordinary least squares has a simple closed-form solution, though that's not such a big deal now as it was in the days of Gauss and Legendre, of course. Squaring however does have a problem as a measure of spread and that is that the units are all squared, where as we'd might prefer the spread to be in the same units as the original data (think of squared pounds or squared dollars or squared apples)

Calculate square root without a calculator

At first glance, this would appear to be so, because the poster's example finds the square root of the two digit whole number 20 instead of the article's example of 645. But learning at least the "guess and check" method for finding the square root will actually help the student UNDERSTAND and remember the square root concept itself! So even though your math book may totally dismiss the topic of finding square roots without a calculator, you can consider to let them practice at least the first method presented here
