We had a faculty member who is teaching chemistry for non-majors ask us to come up with an equation editor that would not require his students to learn LaTex or ML - the subject is tough enough without having the students learn code as well. We went through a lot of candidates and we came to the conclusion that math people don't do visual stuff very well. We sent out the hounds on Twitter and Facebook to track anything down. We went to Europe (via email) and came close to buying something. Finally we found the Daum Equation Editor and what a Daum fine equation editor it is. It is a Google Chrome app so the students will have to have Google Chrome. It allows the students to click on a fraction symbol and fill it in. It saves the equation as text or as an image.
