Jason went diving with his friend, Tom, and they dived negative 10 feet towards the ocean floor. They decided to travel another 20 feet further down, bringing them closer to the ocean floor. Finally, they went another 5 feet lower, which allowed them to reach the ocean floor. In total, how far down did the boys dive, in order to reach the ocean floor?
-10 + -20 + -5 = -35 feet
