Associative property of multiplication

Associative property of multiplication (more detail here) is define that without changing the multiplication appends can be group in any way. According to the Associative property, which comes when doing algebra equation solver, if p * (q * r) then it can be group as
( p * q) * r and there is no change in result .It can describe through an example as follows :
6 * (4 * 5) = (6 * 4) * 5 that is equal to 120 in either form. Associative property of multiplication can take three or more variables or values in expression regardless how they are grouped. You can also play associative property worksheets to improve skills. In the expression there is no change in the answer if parenthesis shows the terms that are considered as single unit .Parenthesis shows the grouping of the values means how the numbers are associated together. Associative property of the multiplication is the most basic property of the computations and it should be remember that grouping in the parenthesis are solve first .This property is the basic number property that is describe the rearrangement of the values .There are some examples of Associative property of multiplication as follows :
Suppose one person go to the super market and purchase milk of 10 dollars and buys the 3 packets of it and sometime after buys 2 packets more and two day after buys 3 packets more, how much money one's give to the cashier? The above situation is associative as
Solution: So he buys the packets as 10 * (3 + 2 + 3) = (3 + 2 + 3) * 10
Both the terms are equal means the answer 80 for each of the expression.
So according to the associative property of multiplication expression can be grouped as any how there is no effect on the answer.
