Answer:
108
Explanation:
Using the distributive property to solve 12 × 9:
- Multiply 9 × 10
- Multiply 9 × 2
- Add the products
1. Multiply 9 × 10:
Multiplying with 10 is easy. Just add a zero to the end of the number it's being multiplied by!
9 × 10 = 90
2. Multiply 9 × 2:
Multiplying by 2 is the same as adding the other number to itself.
9 × 2 = 9 + 9
9 + 9 = 18
3. Add the products:
90 + 18 = 108
Footnote: Writing the equation another way to show the distributive property would look like this:
12 × 9 = 9(10 + 2)
