It's easy to use, it makes math look professional (like you'd see at school) which gives your students confidence when they are trying hard but still failing due its difficulty! You need some training before using this tool as there could be many things hidden from users' eyes so not everyone will understand how everything work together properly or know what each button do exactly etcetera - if one of those happens then I would definitely recommend going through tutorials first since otherwise people might get confused easily with such complicated tools especially during exams where time matters alot more than usual :) Using maths calculators like MATLAB can also provide similar results just easier without spending hours doing calculations manually by hand unlike typing out long numbers into calculator app/programs everytime we want something done while solving equations :D.
