Asubmarine descended 1400 meters below the surface of the water. it then rose 800 meters and then descended 350 meters. what was the submarine's net gain or loss in altitude?

–1200 m

–950 m

–400 m

650 m

well if its below that would be -1400, rising +800 and desending at -350

so the problem is -1400+800-350

-1400+800-350

-600-350

-950
