GATE Virtual Calculator Complete Tutorial 
From this year GATE committee has prohibited the use of conventional calculator and 
introduce virtual calculator which will be available during gate exam. While checking out 
this virtual calculator i found its functioning a bit complex and unusual. Several function 
such as combination, permutation, matrix etc are missing in this calculator. 
Mark my word guys it is near to impossible to operate this calculator correctly on the 
first attempt. So it is mandatory for all of you guys appearing for GATE exam to practice 
this calculator before exam. 
  
Structure of the Tutorial: First we will deal with basic arithmetic operation such 
as plus, minus, division, multiplication, square root, reciprocal then we will move to 
trigonometric, logarithm, exponential and factorial. 
Basic Arithmetic Operation: 
There is a special way of writing number with negative sign. Suppose we want to 
write -25 
1. Write number 25
2. Click on [ +/- ] button.

1. Write number 25
2. Click on [ +/- ] button.
Plus, Minus, Multiplication and Division : 
Now let solve some example to understand some basic feature 
First Example: 
1. Write number 25
2. Click on [+/-] button.
3. Click on [ * ] button –> open bracket [ ( ]  –> Type 50 –> click on [ * ] — > Type
5 –> close bracket [ ) ] –> Click on [ / ] –> Type 4 –> Click on [ = ].
Second Example: 
  Answer is 90 
Button Sequence: 
10    [ + ]   [ ( ]    50    [ – ]    10    [ * ]    [ ( ]    2.6    [ – ]    0.6    [ ) ]    [ / ]     [ ( ]    1.4 
 [ – ]    0.4    [ ) ]    [ = ] 
Power: 
First we will discuss about ( power of 10 ) button then we will move toward power of 
other number. 
Power of 10: Two button has given for Power of 10 function first is [ Exp ] and second 
is [ 10
x
 ]. Let solve an example to see what is the different between them and how does 
they work.

square and cube respectively where as 3rd button is for other numbers. 
Square: First you have to mention x then click on [ x
2 
] to get square of x. For example 
we want to calculate 144
2
 so type 144 then click on [ x
2 
] for result 20736. 
Cube: First you have to mention number then click on [ x
3
 ] to get cube of number. For 
example we want to calculate 125
3
 so first type number 125 then click on [ x
3
 ] for result 
1953125. 
Other: Now we want to calculate 31
4
. Procedure will be same as above but now we 
have to mention power term. So first type 31 then click on [ x
y 
] now mention power 
term which is 4 in this case then click on [ = ] for result 923521.
