A shark rises (goes up) 22 feet from the depth shown in the diagram and then descends (goes down) 11 feet. What is its current depth? (Give your answer as an integer with sign, no units please)
It would be 11 I assume. Because if the “shark” starts at zero on a number line and “goes up” 22 feet it would be going up to 22 on a number line then “descends” down 11 feet you just go back down 11 feet on the number line. To find a total of 11.
