An irrational number is a real number that cannot be written as a ratio of two integers. Unlike rational numbers, the decimal form of an irrational number does not terminate or repeat. Examples of irrational numbers include π (pi), √2 (square root of 2), and e (Euler's number). Non-negative integers refer to the whole numbers starting from zero, and their negatives are their opposites.
