Whole numbers include natural numbers that begin from 1 onwards. The only difference between whole numbers and natural numbers is that the set of whole numbers contains an extra number which is 0. Since, LHS = RHS, 9 = 9, thus, a × (b + c) = (a × b) + (a × c), for the given whole number values. That means, we can add whole numbers in any order. The sum and the product of any three whole numbers remain the same though the grouping of numbers is changed. This property also holds true for multiplication, but not for subtraction or division. Zero is very odd indeed. And even some apparently common-or-garden integers such as 37 have special properties. How Numbers Work takes a tour of this mind-blowing but beautiful world of numbers and the mathematical rules that connect them. The sum and product are always whole numbers! Therefore, among the given numbers, the whole numbers are, (0, 3, and 5). We know that on subtracting one positive integer by another, we may not get their difference as a positive integer, similarly, on dividing one positive number by another, we may not get the quotient as a defined number for example in the case of 13/0. This book offers targeted instructional strategies based on the five NCTM process standards and includes four units, each containing: A diagnostic test in a multiple-choice format An item analysis table that correlates incorrect test ... The sum of the addition of two or more whole numbers is always a whole number. Natural numbers refer to a set of positive integers and on the other hand, natural numbers along with zero(0) form a set, referred to as whole numbers. When a whole number is multiplied to 0, the result is always 0, i.e., x.0 = 0.x = 0. Whole numbers are a part of real numbers that do not include fractions, decimals, or negative numbers. When a whole number is added to 0, its value remains unchanged, i.e., if x is a whole number then x + 0 = 0 + x = x. In mathematics, the number system consists of all types of numbers, including natural numbers and whole numbers, prime numbers and composite numbers, integers, real numbers, and imaginary numbers, etc., which are all used to perform various calculations.
