Simple Math Operations

Great job so far! In Python, performing math operations is straightforward yet powerful, perfectly suited for managing tasks in our grocery store.

We can utilize basic arithmetic operators for diverse calculations:

+ for addition;
- for subtraction;
* for multiplication;
/ for division.

Let's see Alex demonstrate these basic arithmetic operators:

Now, it's your turn to practice using them. To display the results of our calculations, we will be using the print() function. Unlike strings (i.e., text), mathematical expressions do not require quotation marks. We will learn more about this later in the course.

Let's explore some practical examples from our grocery store setting:


              1234567891011
            
# Addition: Calculate the total inventory of apples and oranges.
print(150 + 230)

# Subtraction: Determine how many apples remain after selling 123.
print(150 - 123)

# Multiplication: Compute the total cost for 15 packs of butter, each priced at $2.25.
print(15 * 2.25)

# Division: Find the average price of 4 bananas if the total cost is $4.60.
print(4.60 / 4)

Now, it's your turn to complete the following mathematical operations. Fill in the blanks to complete the print statements and run the code:

Tarefa

Use addition to calculate the total cost of milk ($5.42) and bread ($4.39).
Use multiplication to calculate the cost of a 3.5-pound bag of oranges ($1.20 per pound).
Use division to calculate the average cost per item if a customer bought 5 items and spent a total of $55.
