sir , i want my FX -991 ms scientific calculator to store scientific formulaes and read PDF format . If any one will do this we will not have to mug formulaes and [url removed, login to view] a memory based calculator is not an option because that one is not allowed in Engineering Exams . Just working like a diary (digital) or a small mobile type working displaying its content on simple screen of my calculator.
Look I want my calculator to get advanced . It might have a memory card reader . I can use computer for writing texts but it should display at the time of exam .It must look ordinary from outside case ie. dimensions are almost fixed.
