How do we solve diamond problems?

First you will have a shape that look like a diamond (like the picture below). You will notice that 2 of the spaces are filled in. You have to use the pattern to be able to fill the other two out. The pattern is to have the two other numbers to add to the number on top and to be able to multiply to the number on the bottom. You do this by using the factors of the number you are going to multiply.
 
For example you will multiply 3 and 4 which gives you 12 which would go on the bottom. Then you add 3 and 4 which would be 7.
For example you have to figure out what can be multiply to get 5 and then what can also be added to 6. So first you use the factors of 5 which are 5 and 1 , so when you multiply 5 and 1 you get 5, and when you add 5 and 1 you get 6. So the only two numbers you can use to to fill the diamond out correctly if 5 and 1.
