very unnecessary complex ways to find the solution
it does every calculation needed but I got it instead of fx991ex and it is very complex to use to do simple differentiation you have to press so many buttons to get to it and its not clear I had to google it to know where it was while ALL the other calculators have the differentiation and integration as a one button Also to change the format from decimals to fractions and the other way you have to press many buttons it is the same for Eng notation
