Real Numbers Classification Diagram - Rational vs Irrational Numbers #3336485 (License: Personal Use)

This educational diagram organizes real numbers into two main categories: rational (including natural numbers, whole numbers, integers, and fractions/decimals that terminate or repeat) and irrational numbers (non-repeating, non-terminating decimals like π or √2). The nested ovals visually emphasize set inclusion: every natural number is a whole number, every whole number is an integer, and every integer is a rational number. The light blue section on the right isolates irrational numbers, which cannot be expressed as simple fractions.

Used in middle school to college-level mathematics curricula, especially in introductory algebra or number theory lessons. Matches user intent for visual learning, homework help, or teacher resource preparation.
