Question

Which of the following depicts associative property under addition?

• A. $a+b=b+a$
• B. $a+0=0+a$
• C. $a+(b+c)=(a+b)+c$
• D. $a+(b+c)=a+(b+c)$

Answer 1

Answer: (C)

$a+(b+c)=(a+b)+c$

Associative property for addition states that for any three numbers, it does not matter which two are added first and then their sum is added to the third integer the final result will be same
$\therefore a+(b+c)=(a+b)+c$
