Which calculator should be used for maths optional?

Senior players please help us choose a good non programmable scientific calculator.


  • I read somewhere in quora that 'casio fx 991ES plus' is good for Maths. But would like others to throw more light into it as I am also now in this preparation.
  • Casio fx 991 ES should do the work as it has all the fuctions and equations can be saved and solved simultaneously in it..using it from 2 years...cost is around 750 rs...
  • @shubh04 I have bought this calculator 2 days back. I started with Newton Raphson - Numerical Analysis but somehow I am not able to solve quadratic equations(linear equations I am able to solve). I followed some youtube videos but somehow it is giving me SYNTAX ERROR. Is there some problem with the calculator ? Please give your feedback.
  • @abias first go to mode option then select option no 5 i.e EQN then choose the format of eqn.for quad eqn it is option 3...then put the values of a,b,c and u will get the solution...hope it helps....
