So in step \(\large A\) the 4 was `distributed` to each term inside the brackets. Can you think of what property that might be? :) `Distributing` hmmmmmmm

Step B is a little trickier. They `rearranged` the order of the addition. You can do this based on the fact that addition can happen in any order you want. \(\large 2+3+5 \qquad = \qquad 5+2+3\) The numbers can `commute` ... Blah I can't think of a better way to say that lol It's the `Commutative Property`

Step \(\large C\), the 4 is now `associating` with the 3 instead of the 4x. Can you think of what property this might be? c;

I'm not sure what property that is in part \(\large D\). It's just addition being performed. I think it's called the `Additive Identity Property`. I better look that up to be sure though..

No that's not right, that property involves adding 0 to something.

Yah I dunno, maybe it's just the `Addition` property or something :\
