Lets think about how YOU could work this out.

**THink about the multiply first.**

They multiply to a positive number so that means that they must both be positive OR both be negative.

They ADD to a positive number too **so they both must be positive**.

**Back to multiply**

so we have

1 and 30

2 and 15

3 and 10

5 and 6

and they are the only factors of 30. Which of these adds to 11?
