All our little STEM learners want to help this engineer with the problem he has. The problem is that he has too many solutions, and he has to compare to the pros and cons of each to decide which is the best. Your little engineer will choose the correct number to finish the greater than/less than/equal to equations, and then they'll help him decide which solution will be the best for him to go with.
