Question

show that 13-(6-4)≠(13-6)-4

Answer 1

Hi friend!!!

13-(6-4)=13-(2)=11

Now,(13-6)-4 =(7)-4=3

so, 11≠3

so, 13-(6-4)≠(13-6)-4

By this,we can conclude that subtraction doesn't obey associative law



I hope this will help u ;)

Answer 2

lhs                                      =                           rhs
13-(6-4 )                                                   (13 -6)-4 
13-6+4                                                       7-4
11                                                                 3

so 11 is not equal to 3
