A teacher's review

Review by Manish Kumar on 28th April, 2017

I had first saw this Casio Graphing Calculator in one workshop in a school, and was very impressed with the advanced function it has. I have been using GeoGebra for teaching – but Casio fx CG20 graphic Calculator has so many more features including Geometry, Matrix, Statistics, Vector & Complex Calculation. I am using this to teach my students.Expand

Fast and Easy

Review by Sanjay R on 28th April, 2017

This is by far the easiest graphing calculator to handle I have seen. I as a teacher have used all the previous models of graphing Calculator from various company, but casio graphic calculato fx CG 20 stands alone. Great visualization, quick calculation, quick mode settings, and amazingly fast statistics. I bought this for my daughter who is appearing in AP in May. The best part was – she dint need any handholding, unpacked it, and get going. The design and UI and real intriguing and self-explanatory. Thumbs upExpand
