This python program will do arithmetical operations.

Information & Algorithm

The arithmetic operations are performed by calculator where we can perform addition, subtraction, multiplication and division. This example shows the basic arithmetic operations i.e.

Addition
Subtraction
Multiplication
Division

Let's understand the following example.

Program Code

# Store input numbers:  
num1 = input('Enter first number: ')  
num2 = input('Enter second number: ')  
  
# Add two numbers  
sum = float(num1) + float(num2)  
# Subtract two numbers  
min = float(num1) - float(num2)  
# Multiply two numbers  
mul = float(num1) * float(num2)  
#Divide two numbers  
div = float(num1) / float(num2)  
# Display the sum  
print('The sum of {0} and {1} is {2}'.format(num1, num2, sum))  
  
# Display the subtraction  
print('The subtraction of {0} and {1} is {2}'.format(num1, num2, min))  
# Display the multiplication  
print('The multiplication of {0} and {1} is {2}'.format(num1, num2, mul))  
# Display the division  
print('The division of {0} and {1} is {2}'.format(num1, num2, div))

Output

Enter first number: 10
Enter second number: 20
The sum of 10 and 20 is 30.0
The subtraction of 10 and 20 is -10.0   
The multiplication of 10 and 20 is 200.0
The division of 10 and 20 is 0.5

Explanation

In the above code, we have taken the user input as an integer using the input() function. Then, we have performed the arithmetical operation on the given numbers and print the result using the print statement. We used the format() method to format the string

How to learn from this program

First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.

Practice suggestion

After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
