GATE Virtual Calculator – Candidates appearing for the GATE 2023 Exams are not allowed to take certain items into the hall, and the calculator is one such product. However, candidates are permitted to access the GATE calculator. Now, the question arises, what is a virtual scientific calculator? Since most of the questions asked in the GATE exam are numerical-based, a calculator is required to answer the exams. For this reason, the exam authorities will provide access to a unique feature to the candidates, and this is the GATE virtual calculator for PC. This feature has been made available to the GATE aspirants since 2016.

However, since this GATE calculator in the GATE exam is a complicated device, one needs to know how to use it. Keeping this in mind, in this article, we have given the complete details about the virtual calculator for GATE download for PC, and how to use it.

Specifications of GATE Virtual Calculator

To understand what a GATE scientific calculator is or how to use it properly, the candidate will first need to know more about the GATE calculator for PC.

  • Candidates who appear for the GATE exams will be allowed by the authorities at the exam centre to access the GATE calculator in the GATE exam.
  • The keys to operate simple functions can be found on the right side of the GATE virtual calculator.
  • For scientific operations or other functions, the keys will be available to the left side of the GATE virtual calculator.
  • Since there are separate keys for Inverse functions, the candidates are not required to click on the SHIFT or INV keys.
  • Inverse functions are below the respective functions. Given is the example where ‘sin’ is now available, sin-1 can be found below, as per the calculator.
  • All the trigonometric functions can be found grouped.
  • Hyperbolic functions are also grouped in the virtual calculator.
  • Two display boxes are shown at the top of the virtual calculator, where one package depicts the sequence of the keys that the candidate presses for reference.
  • Another box shows the actual values that are entered or obtained after completion of the calculations.
  • Here we have provided screenshots of at least one calculation given below.

Given below are the examples for these calculations:

    1. Enter ‘C’ to clear all inputs
    2. Enter (←) to delete the last digit entered in the input.

Tips to Use GATE Virtual Calculator Effectively

We have listed a few tips and tricks to use the GATE calculator to calculate the result as soon as possible. This can help candidates to save time and use it for a better exam paper. Candidates can follow these effective tips from the GATE calculator:

  • Press [C] at the start of a calculation to clear any previously calculated value
  • Usage of the predefined operators can help in fast calculations. E.g., π, log, ln, n! 
  • Try to put brackets for the complex operators to avoid wrong calculations
  • Use the memory keys for lengthy calculations

Memory Keys (MC, MR, MS, M+, M-) in GATE Calculator

  • Press MC to clear the memory
  • Press MS to store the number in memory
  • Press MR to read the number from the memory
  • Press M+ to add the memory to the number available on display, then store it in memory
  • Press M- to subtract the number on display from the memory value and then store it in memory
