Calculation of Water Level Change in the River

To calculate the change in water level in the river over two days, we need to subtract the initial water level from the final water level.

Given the information provided: - Yesterday, the water level changed by -20 centimeters. - Today, the water level changed by -10 centimeters.

To find the total change in water level over two days, we add the changes together: - Yesterday: -20 centimeters - Today: -10 centimeters

To calculate the total change, we add the two values: - Total change = -20 centimeters + (-10 centimeters)

The total change in water level over two days is -30 centimeters.

Please note that the information provided does not specify the initial water level, so we are unable to determine the exact water level after the change.
