Associative Property of Rational Numbers Associative Property Associative property of rational numbers states that when three or more rational numbers are added or multiplied the result remains same irrespective of how they are grouped. However, in the case of subtraction and division if the order of the numbers is changed then result will also change. […]

Commutative Property of Rational Numbers Commutative Property The commutative property of rational numbers states that when any two rational numbers are added or multiplied in any order the result we get same result. In case of subtraction and division, if order of numbers is change the result will also change. We will understand these properties […]

Subtraction – Properties Properties of Subtractions 1. Subtracting 0 from any number, gives the number itself, means difference is nothing. 2. When we subtract any number from itself the result is zero, means difference is zero. 3. When we subtract 1 from any number, we get just before it, and the difference always equals the […]
