Most of these problems are the commutative property:

Addition
a + b = b + a

Multiplication
a * b = b * a

and the associative property:

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

Multiplication
(a * b) * c = a * (b * c)

There's also the Identity property:

Addition \ Subtraction:
a + 0 = a \ a - 0 = a

Multiplication \ Division:
a * 1 = a \ a / 1 = a
