Open in App
Solution
If a = -8 , b = -7 ,c = 6
(a+b) + c
= ( -8 + -7 )+6
=( -15 ) +6
= -9
a + ( b + c )
= -7 + ( -8 + 6 )
= -7 + ( -2 )
= -9
so (a+b) + c = a + ( b + c )
hence verified
If a = -8 , b = -7 ,c = 6
(a+b) + c
= ( -8 + -7 )+6
=( -15 ) +6
= -9
a + ( b + c )
= -7 + ( -8 + 6 )
= -7 + ( -2 )
= -9
so (a+b) + c = a + ( b + c )
hence verified
