Python is a high-level programming language that is widely used for a variety of applications. One of the core concepts of programming in Python is performing arithmetic operations.
Whether you’re just starting out with Python or looking to improve your skills, it’s essential to have a good understanding of basic arithmetic operations. In this article, we’ll provide you with Python arithmetic operations simple calculation exercises that will help you improve your skills.
1. Addition
Addition is one of the most basic arithmetic operations in Python. You can add two numbers together using the “+” operator. For example:
a = 5 b = 10 c = a + b # c is now 15
Exercise 1: Write a program that asks the user for two numbers and adds them together.
2. Subtraction
Subtraction is another basic arithmetic operation in Python. You can subtract one number from another using the “-” operator. For example:
a = 10 b = 5 c = a - b # c is now 5
Exercise 2: Write a program that asks the user for two numbers and subtracts the second number from the first.
3. Multiplication
Multiplication is used to find the product of two numbers. In Python, you can use the “*” operator to multiply two numbers together. For example:
a = 5 b = 10 c = a * b # c is now 50
Exercise 3: Write a program that asks the user for two numbers and multiplies them together.
4. Division
Division is used to find the quotient of two numbers. In Python, you can use the “/” operator to divide one number by another. For example:
a = 10 b = 5 c = a / b # c is now 2.0 (note the decimal)
Exercise 4: Write a program that asks the user for two numbers and divides the first number by the second.
5. Modulo
The modulo operation returns the remainder of a division operation. In Python, you can use the “%” operator to perform the modulo operation. For example:
a = 10 b = 3 c = a % b # c is now 1
Exercise 5: Write a program that asks the user for two numbers and returns the remainder when the first number is divided by the second.
6. Exponents
Exponents are used to raise a number to a power. In Python, you can use the “**” operator to perform exponentiation. For example:
a = 2 b = 3 c = a ** b # c is now 8
Exercise 6: Write a program that asks the user for two numbers and raises the first number to the power of the second.
7. Integer Division
Integer division is similar to regular division, but it returns the quotient as an integer. In Python, you can use the “//” operator to perform integer division. For example:
a = 10 b = 3 c = a // b # c is now 3
Exercise 7: Write a program that asks the user for two numbers and performs integer division.
8. Rounding Numbers
Python provides two functions for rounding numbers: “round()” and “int()”. The “round()” function rounds a number to a specified number of decimal places, while the “int()” function rounds a number down to the nearest integer. For example:
a = 3.14159 b = round(a, 2) # b is now 3.14 c = int(a) # c
Exercise 8: Write a program that asks the user for a number and rounds it to the nearest integer.
9. Order of Operations
In Python, arithmetic operations follow the standard order of operations: parentheses, exponents, multiplication and division (performed left to right), and addition and subtraction (performed left to right). For example:
a = 10 + 2 * 3 # a is 16 (2 * 3 is performed first) b = (10 + 2) * 3 # b is 36 (parentheses are performed first)
Exercise 9: Write a program that asks the user for three numbers and performs the following calculation: (number1 + number2) * number3
.
10. Combining Arithmetic Operations
You can combine multiple arithmetic operations in a single expression. For example:
a = 5 + 10 * 2 # a is 25 (10 * 2 is performed first) b = (5 + 10) * 2 # b is 30 (parentheses are performed first) c = (5 * 2) + 10 # c is 20 (5 * 2 is performed first)
Exercise 10: Write a program that asks the user for three numbers and performs the following calculation: number1 + (number2 * number3) / number4
.
