Distributive property of multiplication
Distributive property of multiplication
Breaking down multiplication problems into smaller, easier parts by separating one of the factors into added numbers, and then multiply them separately and finally sum the products together. For example, 4 x (2+3) = (4x2) + (4x3).

Equation based on array 3×9
3 x 9 can be split into 3 x (5 + 4) to get 15 + 12 = 27. This is another example of distributive property.

Study Notes
Basic Understanding
- A basket with 4 rows of 7 apples each contains a total of 28 apples.
- A garden with 6 rows of flowers, each containing 8 flowers, has a total of 48 flowers. This can be solved using the distributive property (6 x 8 = 6 x (5 + 3)).
Using Arrays
-
The completed equation using the array:
- 3 × 9 = 3 × (5 + 4)
- 3 × 9 = (3 × 5) + (3 × 4)
- 3 × 9 = 15 + 12
- 3 × 9 = 27
-
Splitting 5 rows of 6 desks:
- 5 × 6 = 5 × (3 + 3)
Math Stories
-
Theo has 4 plates with 8 cookies each, for a total of 32 cookies. Using the distributive property:
- 4 × 8 = 4 × (5 + 3)
-
Robin's method of finding 7 × 6 by multiplying 7 × 5 and 7 × 1 makes sense. This is also a form of the distributive property.
-
Solving to check: 7 × 6 = 42
Matching
- 4 × (2 + 3)= 20 (Matches with A)
- 6 × (3 + 5) = 48 (Matches with C)
- 3 × (4 + 6) = 30 (Incorrect match, should be B, but no other option)
