Verify using an example that Vector a • (Vector b • Vector c) = (Vector a • Vector b) • Vector c is not true. Explain your reasoning both numerically and by using the definition of the dot product. I am very confused as to what this means?! Thanks for the assistance.

Dot Product 
billy,
It wants you to substitute values (can be anything as far as I know) for each vector into that equation, then explain based on what you know of the definition of a dot product its properties.
For example:
<2,3> dot (<1,4> dot <3,3> = (<2,3> dot <1,4>) dot <3,3>
Work that out, and the two sides should be different answers. Then explain why that is...I'm guessing due to that multiplication property or something along those lines...

Sick Sick,
Awesome! Thanks, billy!
