2- When you slice or cut a solid with a plane, you obtain a shape which is known as "Cross section".

You're using the commutative property when you swap the order of factors in a multiplication:

and you use the associative property when you regroup the products of more than 2 factors in a different way:

So, you're constantly alternating between associative and commutative. Try to see which property you're using in the first step, and then keep alternating between the two!
