3. Distributive Property
Says that multiplying a sum (or difference) by a number is the same as multiplying each number in the sum (or difference) by that number and adding (or subtracting) the products.

4. Example (top of page 157) 6 x 18 6 x (10 + 8)
Think of 18 as
6 x (10 + 8)
Distribute the 6 to both the 10 and the 8: (6 x 10) + (6 x 8)
YOU TRY:
4 x 24
Think of 24 as
4 x ( )
Distribute the 4 to both the 20 and the 4: (4 x 20) + (4 x 4)
Solve: = 96

5. Guided Practice #1 12 x 308= 12 x ( ? + 8) 12 x 308= 12 x (300 +8)
2. Solve it:
(12 x 300) = 3600
(12 x 8)= 96
= 3696

6. So how do I apply this? Try it on your own: 4 x 105
Break apart the 105 into
Now distribute the 4: (4 x 100) +(4 x 5)
Solve it: = 420

7. Order of Operations Pg

8. Order of Operations Definition:
It states that when using the order of operations, do the operations inside of the parentheses first.
12 / 4 + (9 - 2) x (3 + 5)
12 / x 8
Remember to rewrite the operations not yet performed.
Then, you multiply and divide in order from left to right.
12 / x 8
= 59

9. How do I apply this?
Guided Practice: name the operation you should do first.
6 + 27/3
Division
5 x /6

17 –(4 + 3)
