A gecko lays 30 eggs per year. 20 percent of them are infertile, and a third of the remaining eggs will not hatch due to calcification issues.  How many eggs actually hatch?
Infertile:30(.20)=6
30-6=<T>subtract(30, 6)=24 eggs remain
Calcification Issues:24(1/3)=8
24-8=<T>subtract(24, 8)=16 eggs that will hatch
