The students in my class worked in groups of three and one group came up with a solution. Using trial and error, the group started with the numbers 6 and 9. Once they got the first answer of 15, they worked the order of the numbers to get all of the correct answers. 6+9=15, 9+11=20, 11+12=23, 12+4=16, 4+14=18, and 14+7=21.
