Associative Law of Addition:

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

Commutative Law of Addition:

a + b = b + a

Additive Inverse:

a + (-a) = 0

Zero Property:

a + 0 = a

Subtraction is basically the same thing as addition.

a - b = a + (-b)

Instead of subtracting b, you add its additive inverse.

example 10, if you add a negative number to 10 then you're just subtracting from it. 10+-2=8 If you take a negative number like -10 and add a negative number you're adding to the ammount that isn't there, -10+-4=-14. But when you add a positive to a negative you're just getting rid of the negative number. -10+20=+10. Get it?

You do this operation after a couple of others:

First do whatever you find in parentheses

Then do any multiplication/division, followed by addition/subtraction.

If you add one, then you include it with others. If you subtract one, then you take it away.
