Question

For any whole number a,b,c is it true that (a+b)+c=a+(c+b)? Give reason

Answer 1

$\huge\underline\red\bold$

yes, (a + b) +c = a + ( c + b)

a = 3, b = 2, c = 4

( 3 + 2) + 4 = 3 + ( 4 + 2)

5 + 4 = 3 + 6

9 = 9

Answer 2

yes, ( a + b ) + c = a + ( c + b )

a= 3 ,b = 2, c = 4

( 3 + 2 ) + 4 = 3 + ( 4 + 2 )

5 + 4 = 3 + 6

9 = 9.
