WebLemma 1.3 (commutativity of addition). For any x;y2N, x+ y= y+ x. Proof. As always we start with a subset Sof N. S= fy2N j8x2N; x+ y= y+ xg To use induction, we need to check two things. Of course, if we show S= N, we would have proved the lemma. Step 1: 1 2S. WebDistributive Law. The "Distributive Law" is the BEST one of all, but needs careful attention. This is what it lets us do: 3 lots of (2+4) is the same as 3 lots of 2 plus 3 lots of 4. So, the 3× can be "distributed" across the 2+4, into 3×2 and 3×4. And we write it like this: s/2007 s 3

WebHere's a quick summary of these properties: Commutative property of addition: Changing the order of addends does not change the sum. For example, 4 + 2 = 2 + 4 4+2 = 2 +4. Associative property of addition: Changing the grouping of addends does not change the sum. For example, (2 + 3) + 4 = 2 + (3 + 4) (2+3)+4 = 2+(3+4).
