# HackerRank Solution: Python Arithmetic Operators

Author: Bashir Alam

## Question: Python Arithmetic Operators [Introduction]

The provided code stub reads two integers from STDIN,a and b. Add code to print three lines where:

• The first line contains the sum of the two numbers.
• The second line contains the difference of the two numbers (first - second).
• The third line contains the product of the two numbers.

Example:

`a = 3b = 5`

print the following:

```8
-2
15```

Input format:

The first line contains the first integer, a.
The second line contains the second integer, b.

Constraint:

1<=a <=10^10

1<=b<=10^10

Output format:

Print the three lines as explained above

Sample Input:

```3
2```

Explanation:

3+2 --> 5

3-2 --> 1

3*2 --> 6

## Possible solutions

Now we will go through the following solutions: The following code is given in the hacker rank:

``````if __name__ == '__main__':
a = int(input())
b = int(input())``````

We will use two different possible methods to solve the problem.

1. Using single print method
2. Using multiple print methods

Now we will go through each of the methods.

### Solution-1: Using singple print method

Now we will solve the problem and then will explain the code:

``````if __name__ == '__main__':
a = int(input())
b = int(input())

print(str(a+b)+"\n"+str(a-b)+"\n"+str(a*b))``````

This code defines a simple program that prompts the user to enter two integers, `a` and `b`, and then prints their sum, difference, and product. The program begins by reading in the two integers using the `input()` function, which reads user input from the command line as a string. The program then converts these strings to integers using the `int()` function and stores them in the variables `a` and `b`. The program then calculates the sum, difference, and product of `a` and `b` and prints the results using the `print()` function. The `str()` function is used to convert the results to strings so that they can be printed. The `\n` characters in the `print()` statement are used to insert newline characters, which cause the output to be printed on separate lines.

### Solution-2: Using multiple print methods

Now we will use multiple print methods to print the value:

``````if __name__ == '__main__':
a = int(input())
b = int(input())

print(a+b)
print(a-b)
print(a*b)``````

This code defines a simple program that prompts the user to enter two integers, a and b, and then prints their sum, difference, and product. The program begins by reading in the two integers using the `input()` function, which reads user input from the command line as a string. The program then converts these strings to integers using the `int()` function and stores them in the variables `a` and `b`. The program then calculates the sum, difference, and product of a and b and prints the results using the `print()` function. The `print()` function prints each result on a separate line because each call to `print()` is on a separate line in the code.

## Summary

In this short article, we discussed how to solve Arithemetic operator problem on Hacker rank. We solved the error using two methods and explained both methods.
