Associative Property
Associative Property:
It states that you can add or multiply numbers regardless of how they are grouped. In both the groups the sum is the same. Addition and multiplication are associative for rational numbers. Subtraction and division are not associative for rational numbers.
Rational numbers follow the associative property for addition and multiplication.
Suppose x, y and z are rational then for addition: x+(y+z)=(x+y)+z
For multiplication: x(yz)=(xy)z.
Some important properties that should be remembered are:
For example, given numbers are 5, -6 and 2/3( 5 – 6 ) + 2/3= -1 + 2/3= – 1/3Now, 5 + ( -6 + 2/3 )= – 1/3
