Math stuff

Post by 休み...? on Wed Nov 03, 2010 7:07 pm

^^ I decided to post some fundamental math things to reinforce knowledge!

Associative Property of...

Addition
(a + b) + c = a + (b + c)

Multiplication
(ab)c = a(bc)



Commutative Property of...

Addition
a + b = b + a

Multiplication
ab = ba



Distributive Property of Multiplication
a(b + c) = (ab) + (ac)



Identity Property of Multiplication

Addition
a + 0 = a

Multiplication
1a = a



Order of Operations
  1. ()
  2. ab, a/b
  3. a+b, a-b



Zero Product Property
0a = 0

I... hate math. It drives me insane when it does not have to do with money.

Logs isn't that bad. Just one basic rule and principle to follow. How to apply to real life? Surveyors and engineering I believe.
