What does it mean
to say that multiplication is commutative?
 |
It is the property
which states that for all real numbers a, b, and c,
their
product is
always the same, regardless of their order:
a * b * c = a * b * c |
|
In other words... |
 |
|
If we have some numbers
that we are multiplying together, it doesn't matter if we change
their order because the answer will be the same. |

1 * 2 * 3 |
= |
3 * 2 * 1 |
| 2 * 3
|
= |
6 * 1 |
| 6 |
= |
6 |
 |
10 *
2.5 * 3 |
= |
3 * 2.5 * 10 |
| 25 * 3
|
= |
7.5 * 10 |
| 75 |
= |
75 |
 |
| (18 *
6) + 3 |
= |
(6 * 18)
+3 |
| 108 + 3
|
= |
108 + 3 |
