Distributive Property
To multiply a sum (or difference) by the same factor, we multiply each addend (or the minuend and the subtrahend) by that factor and then add (or subtract) the products
The distributive property applies to binary operations such as multiplication and, partially, division.
Distributing multiplication over addition and subtraction
In the case of multiplication, the distributive property states that, given three numbers π, π and π,
and, symmetrically,
Since multiplication is commutative, it does not matter whether the factor π is to the left or the right of the parentheses.
Distributing a factor over a sum
That the sum (πβ π)+(πβ π) is equal to πβ (π+π) can be understood intuitively through a geometric representation of this equality. Letβs set π=4, π=3 and π=5. For the distributive property, we have:
from which, carrying out the operations, we obtain:
The product πβ π can be represented by a rectangle of area π΄=12 and sides 4β 3. Similarly, the product πβ π by a rectangle of area π΄=20 and sides 4β 5. Thus, the productβ¦
