What has changed, the grouping or the order?

hartnn · Answer

commutative :  m*n=n*m

identity : a*1 =a 

associative : m+ (n+p) = (m+n) + p

now choose :)

commutative?

mathstudent55 · Answer

Change of order  ---> commutative
Change of grouping  ---> associative

mathstudent55 · Answer

correct

mathstudent55 · Answer

It IS commutative. The grouping has not changed. It is the order that changed. Look at what is inside the parentheses on both sides of the equal sign.

hartnn · Answer

yeah, sorry, its commutative :)

mathstudent55 · Answer

The use of parentheses in this question is to diguise the commutative property into looking like the associative property.
