Working with Numbers: Everyday Math
Understanding how to perform calculations is essential for using Python in your daily life. Python's arithmetic operators let you easily handle tasks like adding up shopping totals, working out budgets, or figuring out discounts. The main arithmetic operators you will use are:
- Addition (
+): adds two numbers; - Subtraction (
-): subtracts one number from another; - Multiplication (
*): multiplies two numbers; - Division (
/): divides one number by another; - Parentheses (
()): control the order of operations, just like in standard math.
You can combine these operators to solve everyday math problems quickly and accurately.
1234567891011121314# Basic arithmetic operations total = 20 + 15 # Addition difference = 20 - 5 # Subtraction product = 4 * 6 # Multiplication quotient = 18 / 3 # Division # Using parentheses to control order of operations result = (2 + 3) * 4 # Parentheses change the order print("Total:", total) print("Difference:", difference) print("Product:", product) print("Quotient:", quotient) print("Result with parentheses:", result)
When you work with numbers in Python, you will encounter two main types: integers (whole numbers like 5 or -2) and floats (numbers with a decimal point, like 3.14 or -0.5). It's important to be aware of these types because certain operations, especially division, can produce different results depending on the input. For example, dividing two integers with / will always result in a float, even if the result is a whole number. This can affect how your results look and how you use them in further calculations.
12345678910111213# Calculate a grocery bill with tax and a discount subtotal = 50.00 # base price of groceries tax_rate = 0.07 # 7% tax discount = 5.00 # $5 discount tax = subtotal * tax_rate total_before_discount = subtotal + tax final_total = total_before_discount - discount print("Subtotal:", subtotal) print("Tax:", tax) print("Total before discount:", total_before_discount) print("Final total after discount:", final_total)
1. Which operator would you use to find the remainder of a division in Python?
2. What is the difference between an integer and a float in Python?
3. Fill in the blanks to complete a calculation for a discounted price.

Can you explain the difference between integers and floats in more detail?
How can I use these arithmetic operators for more complex calculations?
Can you show more examples of using parentheses to change the order of operations?
Fantastisk!
