Order of Operations
Some arithmetic expressions appear to allow dierent interpretations. For example, most people
will simplify 6 3 + 2 as follows:
63+2
=
(6 3) + 2
=
3+2
=
5,
but a few may read 6 3 + 2 as 6 (3 + 2), which equals 1. Most people will simpl

The Distributive Law
If x, y and z are any numbers, then
x (y + z ) = x y + x z.
Of course, it does not matter in what order we write the factors in a multiplication, so the distributive law implies that (y + z ) x = x y + x z , and that (y +
