A diver is 15 feet below, sea level the diver then swims up 15 feet to the surface which expression shows the correct sum
To represent the situation, we can use the expression "(-15) + 15" which gives us the correct sum of 0.
To find the correct sum, we need to add the distance below the sea level (15 feet) to the distance the diver swims up to the surface (15 feet).
The expression that shows the correct sum is:
15 feet below sea level + 15 feet to the surface
This can be simplified as:
-15 feet + 15 feet
When we add these two distances together, we get:
(-15 feet) + (15 feet) = 0 feet
Therefore, the correct sum is 0 feet. This indicates that the diver ends up at the sea level after swimming up 15 feet.
The expression that shows the correct sum is:
-15 + 15 = 0
