GATE exam in only a few exams allows candidates to use the virtual calculator. The GATE (Graduate Aptitude Test in Engineering) 2023 exam provides a pathway for qualified aspirants to get admission to postgraduate programs at IISC, IITs, NITs, and many more Government & private colleges. As no physical calculator is allowed in the exam hall, the GATE authority provides the virtual calculator online with the GATE online interface. So candidates must know how to use the GATE virtual calculator provided in the exam and should have a good practice before the exam to minimize calculation error.

Know about the significance of the GATE virtual calculator in the coming sections. Here we are providing tips & tricks, shortcuts, and other important information for using the GATE 2023 online virtual calculator, which will help you to practice accuracy and get familiar with all kinds of operations.

To start practising the GATE virtual calculator during the preparation days, aspirants should have access to the GATE online calculator. Generally, there are two ways you can use the GATE calculator easily during numerical practice.

It is recommended to practice in the GATE virtual calculator app on mobile starting from the preparation days. When candidates are attempting the Gate mock tests, they will feel the differences in using the online calculator with increasing the calculation speed with less time wasted in the calculator.

## 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.
