IIT JAM Chemistry: Learn How to use the virtual calculator. | How to Study for IIT JAM Chemistry PDF Download

IIT JAM exam is conducted in three sections- MCQs, MSQs and NAT-type questions. Numerical answer-type questions are based on real numbers.

Earlier, students had to face a lot of difficulties in solving this section. They were required to calculate the values in a rough paper, which was a time-consuming process.

So, focusing on the difficulty of solving this section, the official authority introduced the IIT JAM Virtual Calculator in 2016.

Here,  we are providing you with the details of IIT JAM Virtual Calculator that will help you to complete your exam within the given time limit.
Contribution of a calculator in JAM Chemistry exam

• Calculator plays a vital role in JAM exam. You might lose very good rank due to a lack of practice on the Calculator, even though you know how to solve the question.

• You must have good amount of practice using an online calculator. Even if you know the concept, formula and everything about a JAM problem, there will be certain questions that you will not be able to solve without a calculator.

• Calculations are sometimes tedious and time taking that’s why JAM provides you the calculator. The major drawback is, that during the exams the virtual calculator has to be used with a mouse. It is like using one finger at 0.5x speed. So, practicing vertical calculator is important.   

•  For trigonometric values like sin and cos angle calculator is important. Also for square, square root, the etc calculator helps you a lot and save your time of calculation.

Essential Characteristics of the IIT JAM Virtual Calculator

 Below we are sharing the characteristics of IIT JAM 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.

• All Functions are grouped together for ease of success.

• Inverse functions have separate keys (no need to press SHIFT or INV keys)

• All trigonometric functions and Hyperbolic functions are together.

• Inverse functions are placed below the respective functions. For example, “sin inv” is placed below “sin”.

• 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.

Important Note: -

•  The IIT JAM Question Papers will be set considering the usage of the online calculator.

• All the necessary functions and operations have been provided.

• Any calculations needed for solving the questions can be carried out using this calculator.

How does Virtual Calculator Works? - Follow the Steps

IIT JAM virtual calculator has all the functions that you will need while calculating the numerical value. You must know all the functions of the calculator so that you can use the calculator without facing any difficulty.

Below, we are providing some examples to understand the functions of the calculator. You should go through the examples and learn from them to practice online:

Have a look at some examples provided: 
Arithmetic Operators (+, - , * , /)

• Calculate 145 * (20-3)/7 + 20

• Enter 145, *, (, 20, -, 3, ), /, 7, +, 20, =

Logarithmic functions (log, ln, log2x, logyx)
Try to use brackets during complex calculations

• Calculate 34 × log5(20) + 50

• Enter 34, *, (, 20, logyx , 5, ), +, 50, =

Trigonometric Operations (sin) Using Deg (degree) mode
Try to use brackets during complex calculations

• Calculate 20 * sin(400) + 55

• Enter 20, *, (, 40, sin, ), + , 55, =

Tips and Tricks for Effective Usage of GATE Virtual Calculator

Here are a few effective tips and tricks to use the GATE virtual calculator in order to produce the desired result as soon as possible so that time can be saved and used for a better attempt at the exam paper. The effective usage of the GATE virtual calculator can be done with the use of the following tips:

• Make sure to press [C] at the start of a calculation.

• Use the predefined operator like π, log, ln, n! for fast calculations

• Try to put brackets for the complex operators to avoid wrong calculations

• Use the following memory keys for lengthy calculations

Memory Keys (MC, MR, MS, M+, M-)

• MC is used to clear the memory.

• MS is used to store the number in memory.

• MR is used to read the number from memory.

• M+ is used to add the memory to the number available on display, then stored in memory.

• M- is used to subtract the number on display from the memory value, and then store it in memory.
