6 x (7 + 3) = (6 x 7) + (6 x 3)
6 x (7 - 3) = (6 x 7) - (6 x 3)
In the example above the 6 has been distributed to both numbers
inside the bracket by multiplication. This would have been
true whatever numbers had been used. So it is said that multiplication
is distributive over addition and subtraction.
real numbers, addition distributes over the maximum operation,
and also over the minimum operation: a + max (b,c) = max (a
+ b, a + c) and a + min (b,c) = min (a + b, a + c).
