A submarine traveling 200 meters below the surface of the ocean increases its depth by 45 meters. Janice says that the new location of the submarine is -155 meters. What error did Janice make? What is the new depth of the submarine?
She SUBTRACTED the increase in depth, when she should've ADDED it!!

This is because the submarine traveled deeper to get to the new DEPTH!
