Whole numbers include all positive integers and zero, while natural numbers only include positive integers. Rational numbers are those that can be expressed as a ratio of two integers, and irrational numbers cannot be expressed as a simple fraction. Real numbers encompass all rational and irrational numbers, while complex numbers include a real part and an imaginary part. **
