Hello everyone, this is to inform you that I have a calculator CASIO fx991ES (the one which is used for extensive mathematical operations). I am a student of Biology so I dont have anything to do with it. Now you must be wondering that why did I buy that. Actually I bought it as a gift for my younger brother (who is pusuing B.Tech) but unforunately this model wasnt allowed in his college. So I thought of passing to a person who can make its use.

(Students at IT-BHU use this model)

I’ll sell the product a reasonable price (with warranty card and cash memo).
