The basic definition is that a rational number can be expressed as a fraction, with integers in the numerator and the denominator; if such a representation is not possible, you have an irrational number. For example, 1/3, 5/2 and 7 (which is equal to 7/1) are rational numbers; the square root of 2, pi, and e are irrational, because it has been proven that none of them can be expressed as a fraction with integers.
The quotient of a nonzero rational number and an irrational number is always an irrational number. This is because dividing a rational number (which can be expressed as a fraction of integers) by an irrational number cannot result in a fraction that can be simplified to a rational form. Therefore, the result remains outside the realm of rational numbers.
An irrational number.
When added to a rational number, any irrational number will produce an irrational number.also, when added to an irrational number, any rational number will produce an irrational number.
It is not an irrational number!
Yes, it will always be irrational.

A positive real number. It can be irrational or rational, even integer.

An irrational number.
The sum of a rational and irrational number must be an irrational number.
No. The sum of an irrational number and any other [real] number is irrational.
rational * irrational = irrational.
No, 3.56 is not an irrational number. 3.56 is rational.
-Pi is irrational, because it does not terminate or repeat. Whenever you multiply an irrational number by a rational number (-1), the result is an irrational number.
A negative irrational number can be thought of as an irrational number multiplied by -1, or an irrational number with a minus sign in front of it.
At least one of the factors has to be irrational.* An irrational number times ANY number (except zero) is irrational. * The product of two irrational numbers can be either rational or irrational.
