Best ResponseYou've already chosen the best response.0@rishi_k texaschic101 Guys, please explain to the asker why it is the answer you proposed. We're not here to give direct answers and the asker is not learning anything. Please, if you know why your answer is correct, explain it. If you don't, leave the question alone. @Tom_Boy_Rebel Associative property of addition is the property that we can regroup the additions differently and still get the same answer. For example, 1+2+3=(1+2)+3=1+(2+3)=6. We can add 1+2=3 and then 3+3=6, or (2+3)=5 and then add 1 to get 6. See http://www.coolmath.com/prealgebra/06properties/03propertiesassociativeaddition01 for more examples.

Best ResponseYou've already chosen the best response.0Then @mathmate Associative property states that for any real numbers A,B&C (A+B)+C=A+(B+C) And (A*B)*C=A*(B*C)
