Remembering your times tables will help you solve problems in this lesson. Let's give this problem a try.
What is 8\times3?
We get the same answer whichever way we look at our array.
This video shows us how to find unknowns using our multiplication and division facts.
Complete the statement with the missing number: 8\times⬚=80
We can write multiplication statements as division statements to help find an unknown.
Turn around facts tell us that for multiplication the order doesn't matter. So for something like 4 \times 5, we can also write it as 5 \times 4 and get the same answer.
