Write a subtraction expression for the vertical distance the shark traveled

Question

a  it at -80 feet, he swims up and jumps out of the water to the height of 15 feet

Answer 1

Take your final height, 15 ft, and subtract your initial height (-80 ft). The equation looks like:

 

15 - (-80)

 

Remember, 2 negatives multiplied together equals a positive, so you are now adding 15 and 80 together, for a height jumped of 95 ft.
