The square root of 25 is 5.
Natural numbers are positive whole numbers (1, 2, 3, 4, 5, ...)
Whole numbers are positive and negative numbers or zero that do not have decimal or fractional parts (...,-3, -2, -1, 0, 1, 2, 3,...)
Integers are positive and negative whole numbers or zero (..., -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5...)
Rational numbers include all integers as well as positive or negative numbers that have fractional parts ( -2.0, -3/4, 0.25, 2.1, 5, etc.)
Irrational numbers are numbers that can not be written as a simple fraction. Its decimal goes on forever without repeating (π = 3.14159....)
5 is a natural number, whole number, integer, and rational number.

You are correct. Whole numbers are the basic counting numbers, 0, 1, 2, 3, .... I made a mistake in typing that statement. I apologize for the confusion.01/22/21
