You can put this solution on YOUR website!
The communtitivue property for multiplication states that the order of the miltiplicands and can be swapped and the resulting product stays the same.
So
A * B = B * A
In your case, that says 7 * 8 = 8 * 7
So if
7+%2A+8+=+56
then the commutitivte property says
8+%2A+7+=+56 as well since you can swap the order of the terms on the left and not change the result.
This property is true for addition and multiplication. It does not hold for subtraction or division.
Hope that helps
