Mathematical Properties/Distributive Property

The Distributive Property means to multiply the number on the outside of the parenthesis, by each term on the inside.

Part I
Directions : ''Rewriting the Equation using the Distributive Property. ''
 * Example: 5 x 73 = (5 x 70) + (5 x 3)

So, for this problem, add a parenthesis, then add "5 x". Then add "7" after the "x", then add "0" and then parenthesis. Now add "+", another parenthesis, "5" and "x", then "3.

It's like breaking down the "73" here. For the first parenthesis problem, add "7", but since there's "3" in "5 x 73", add a placeholder, 0. Then in the second parenthesis, it's "5 x 3", but since there's no number behind the "3", add nothing. Leave 3.

Still don't understand? Take a look at these problems to help you:


 * Example: 6 x 92 = (6 x 90) + (6 x 2)
 * Example: 9 x 25 = (9 x 20) + (9 x 5)
 * Example: 7 x 71 = (7 x 70) + (7 x 1)
 * Example: 4 x 66 = (4 x 60) + (4 x 6)

Part II
Directions : ''Solve for the unknown number. '' 5 x 13 = (5 x _) + (5 x _)
 * Example

This shouldn't be difficult. "13" - for the first equation, remember there's "1", and another number after it: 3. But you need to replace the "3" with "0". So like: (5 x 10) + (5 x 3).

Add "3", since that's the number behind "1", in "13".

This should be easy for you: 5 x d = (5 x 30) + (5 x 9) = d is 39 1 x z = (1 x 60) + (1 x 5) = z is 65 4 x a = (4 x 20) + (4 x 3) = a is 23 9 x u = (9 x 90) + (9 x 4) = u is 94
