📘 Lesson 1

Arithmetic Operators

Perform mathematical calculations on numbers.

Operator	Name	Example	Result
+	Addition	10 + 3	13
-	Subtraction	10 - 3	7
*	Multiplication	10 * 3	30
/	Division	10 / 3	3.333…
//	Floor Division	10 // 3	3
%	Modulus	10 % 3	1
**	Exponentiation	2 ** 8	256

arithmetic.py
a, b = 17, 5
print(a + b)   # 22
print(a - b)   # 12
print(a * b)   # 85
print(a / b)   # 3.4
print(a // b)  # 3
print(a % b)   # 2
print(a ** b)  # 1419857

🔵 Modulus Visualizer — See the remainder

Divide by

💡

The modulus operator % gives you the remainder. Great for checking if a number is even: n % 2 == 0!

📘 Lesson 2

Comparison Operators

Compare values — always return True or False.

Operator	Meaning	Example	Result
==	Equal to	5 == 5	True
!=	Not equal	5 != 3	True
>	Greater than	10 > 3	True
<	Less than	3 < 10	True
>=	Greater/equal	5 >= 5	True
<=	Less/equal	4 <= 5	True

⚠️

Don't confuse = (assignment) with == (comparison)!

📘 Lesson 3

Logical Operators

Combine conditions — and, or, not.

🤝

and

True only if both are True

True and True → True

🔀

or

True if at least one is True

True or False → True

🔄

not

Flips the value

not True → False

logical.py

    age = 20
score = 85
print(age >= 18and score >= 80)
print(age >= 18or score >= 90)
  

True

x %= 7

↓

x = x % 7

💻 Practice

Coding Exercises

⭐ Exercise 1

Odd or Even

Use the modulus operator to check if 47 is odd/even.

n = 47
print(f"{n} is {'even' if n % 2 == 0 else 'odd'}")  # odd

⭐ Exercise 2

Voter Eligibility

Check if age >= 18 AND is_citizen = True.

age, is_citizen = 20, True
can_vote = age >= 18 and is_citizen  # True

⭐ Exercise 3

Predict the Output

Predict: 3 + 4 * 2, (3+4)*2, 2**3**2, 15%4, True and False or True

# 11, 14, 512, 3, True
