7- 3-1 7-2 5 but 7-3-1 4-1 3. Alternatively you can first multiply each addend by the 3 this is called distributing the 3 and then you can add the products. OK let us get some practice.

The turnaround facts eg. These arrays can be expanded to show the relationship between the twos fours and eights multiplication facts. 310 32 30 6 36.

Since multiplication is commutative you can use the distributive property regardless of the order of the factors. 5 10 15 20 25 30 35 40 45 50. 3 10 2 312 36.

Skip Counting by 5s to 50. You can use this fact to help you keep straight that cosecant goes with sine and secant goes with cosine. 7 9 is like two 8s but 7 is 1 smaller than 8 and 9 is 1 bigger than 8.

8 5 13 You can switch the order of the two numbers added above to equal the third number again. How are they related. 2x81x8 168 24 How can you use a 2s fact and 1s fact to find 3x8.
