Below we are sharing the characteristics of IIT JAM 2017 Virtual Calculator, read them carefully: –
All the keys required for simple operations are placed on the right-hand side of the virtual calculator for easy access.
All Scientific functions and operations are separated on the left-hand side of the virtual calculator.
Inverse functions have separate keys (no need to press SHIFT or INV keys)
Functions are grouped together for easy access. All trigonometric functions are together. Inverse functions are placed below the respective functions. For example; “sin inv” is placed below “sin”
Hyperbolic functions are grouped together.
Two display boxes are provided at the top of the virtual calculator. The top box indicates the sequence of the keys pressed (not the actual calculations) and is just for reference.
The display box below it indicates the actual values entered or obtained after calculations.

Points to Be Kept in Mind While Practicing Virtual Calculator
While practicing the virtual calculator, some doubts could arise in your minds. Given below are some important points that will help you in getting the answer to your queries:
This is not a fractional calculator. NAT questions need the answers only in decimal form.
No separate keys are available for converting polar to rectangular form and vice versa. You should use appropriate conversions using the calculator.
Complex numbers cannot be represented in this calculator. All questions relating to any area where complex numbers might be deemed useful, eg.in power systems or other areas, can be solved using this calculator.
Matrices of numbers cannot be represented. The candidates need to carry out all the matrix related calculations manually.
This is a non-programmable calculator. It does not solve any quadratic, cubic or simultaneous equations.
You can’t get a stand-alone calculator app for mobile or computer. You should access the calculator through web.
Web connection is needed only to load the calculator on your webpage on your computer or mobile. Once it is loaded you do not need an internet connection to carry out the calculations.
Any constants needed for solution will be provided in the question paper. Wherever it is not provided then it is expected that the candidates should know the values of the constants.
The keyboard will not be accessible during the entire duration of examination, you need to use the mouse.
You should make sure that the top display area is showing the sequence of the keys pressed and not the formula.
You can use the scribble pad for assistance since the calculator will not store the previous steps.
There is a memory button in the virtual scientific calculator also to store a value.
