Associativity Property - applicable to Addition and Multiplication Only, not for Subtraction and Division

Take an example:

(4+2) + 3 = 4 + (2+3) In both the cases of addition the answer is same i.e. 9. So using brackets if you change association of numbers

then the result does not change.

Take an example of Multiplication:

(4 x 2) x 3 = 4 x (2 x 3) = 24 in both the cases answer is same 24 which bracket you solve first. Hence addition and multiplication

follows associativity property.

Now let's see subtraction:

(4 -2 ) -3 = 4 - (2 -3)

2-3 = -1

4 - (-1) = 5

Hence by changing association in subtraction we get different result hence property of associativity does not hold good in subtraction.

Now let's see division:

(4/2) / 3 is N.E. (Not Equal) 4 /(2/3) So obviously division does not have associativity property.
