it’s easier to use on a cellphone. the scan and solve feature is extremely useful. you line up your camera with the question and press the button to take a picture for the system to scan. if there is an recognizable matches, they will show up. if there is none, you can ask the question to the community or a tutor. if you are using the website, i believe you just type in the text you are trying to find the answer to in the search bar and it is the same deal with results as on mobile.
hope this helped !!
