Once upon a code-time, in the kingdom of Pythonland, there lived a brilliant superhero called Captain Calculator. His job? To help young coders like YOU learn how to do math in Python using powerful magic symbols called operators. 🧙‍♂️🔣

Let’s hop on his math-mobile and go on an adventure through the seven lands of Arithmetic Operators. Each land has a different power. Are you ready? Let’s ride! 🚀

🏰 Land of Addition (+): “The Friendly Joiner”

Captain Calculator says, “This symbol helps you join numbers together.”

print(1 + 1)  # Output: 2

Two little ducks joined flippers. And poof! They became two.

🏜️ Land of Subtraction (-): “The Number Picker”

Sometimes, you need to take something away — maybe a cookie 🍪 from your snack pack.

print(5 - 2)  # Output: 3

Captain Calculator smiled. “Took 2 cookies from 5 — now you have 3 left!”

🏗️ Land of Multiplication (*): “The Fast Doubler”

“When you need more in a flash,” says the Captain.

print(3 * 4)  # Output: 12

Three boxes with 4 apples each — boom! You’ve got 12 apples! 🍎🍎🍎

🌊 Land of Division (/): “The Equal Sharer”

In this land, everyone gets a fair share.

print(8 / 2)  # Output: 4.0

Eight candies, two kids. Each gets four candies. Easy math!

🌀 Land of Modulus (%): “The Remainder Revealer”

Captain Calculator whispered, “This is my sneaky trick. I’ll tell you what’s left after sharing!”

print(10 % 3)  # Output: 1

Shared 10 balloons among 3 kids. One balloon is left behind. 🎈

🌟 Land of Exponentiation (**): “The Power Booster”

When you want to make a number super strong 💪.

print(2 ** 4)  # Output: 16

2 to the power of 4 is like saying: 2 × 2 × 2 × 2. Ka-BOOM! 16! 💥

🧱 Land of Floor Division (//): “The Ground Cutter”

This operator chops off the decimal and gives you just the full parts.

print(7 // 2)  # Output: 3

“Only full pizzas, please!” 🍕

🧪 Captain’s Potion Pack: Compound Assignment Operators

When Captain Calculator is in a hurry, he uses shortcuts like these:

Let’s say we start with:

age = 8

➕ Add and Assign (+=)

age += 2  # Same as age = age + 2

Now age becomes 10. Birthday party time! 🎂

➖ Subtract and Assign (-=)

age -= 3

Back in time? Age becomes 7.

✖️ Multiply and Assign (*=)

age *= 2

Now you’ve doubled! Age is 14.

➗ Divide and Assign (/=)

age /= 2

Split your age in half? Now it’s 7.0 (a float).

💥 Others: %= for modulus, **= for powers, and //= for floor division — all work the same!

📊 Captain’s Treasure Map: Summary Table

Operator What It Does Example Result
+ Add 2 + 3 5
- Subtract 7 - 2 5
* Multiply 3 * 3 9
/ Divide (float) 8 / 2 4.0
% Remainder 9 % 4 1
** Raise to Power 2 ** 3 8
// Divide, Round Down 10 // 3 3

Captain Calculator raised his wand and shouted:

“Now you, my young apprentice, can use Python to do math like a wizard! Go forth and code!”

🧠 Review and Practice Time

  1. What will be printed when you run this code?

    result = 10 % 4
print(result)

  2. Which operator would you use to calculate “3 to the power of 4”?

  3. Fill in the blank to increase count by 5:

    count = 10  
count ___ 5

  4. Guess what this code will output:

    number = 20  
number //= 3  
print(number)

  5. Your turn! Write a Python program that:

    • Starts with score = 5
    • Adds 2
    • Multiplies by 3
    • Prints the final score
