Heya 

The question is about Associative property in addition .

It means that when we group the numbers to make it simpler so however if we change their position the product will remain same 

Ex. ⇒ A + ( B + C ) = A + B + C


Let's understand with an example 


A = 8 

B = 6 

C = 7



8 + ( 6 +7 ) =  8 + 6 + 7 

8 + 13        =     21

21               =    21 


L.H.S. = R.H.S.




Another example 


A = 21

B = 50 

C = 66


21 + ( 50 + 66 )  =  21 + 50 + 66

21 + 116             =    137 

137                     =    137

L.H.S = R.H.S 



Hence proved ! 



Hope it helps :)
