What do our people say?

But anyways, i would want to have an reccomendation, i think it would be great if we can just import a picture then crop it because im really having a hard time re-writing all the equations on my scratch paper since i only have the softcopies of my homeworks that our teacher gave to us.

I'm actually learning here, not like an ordinary app , it's a legendary application, great for explaning problem steps when the teachers not there, it literally could solve anything apart from word equations.
