First we drew all four bags and their numbers. Whenever we used a number we would cross out the number in the bag to keep track on how many numbers we were using. We tried to make thirty first by adding 7+3 and two 5+5 giving us 30. Then the hard part was to make seven but we found out that it was not possible to make seven with four numbers. So we realized that we needed to change the ten. We first lowered the number ten into eight. But we still could not manage to make 37. So we thought maybe we could increase the number ten. So we decided to change one of the tens to eleven, that makes thirty one. Then, we added 3+1 and 1+1 to make 6. 31 added up to 6 makes 37. That's how we solved this problem
