Basic Math Operators in Python -

Intro
Ab tak aap input() lena aur int() / float() me convert karna seekh gaye.
Ab hum Python ko bilkul calculator ki tarah use karenge.
Chinta mat karo. Ye school wali simple math hi hai.

Concept Explanation

WHY: Operators ki zaroorat kyun hoti hai?

Socho aapke paas 2 numbers hain.
Aap unko jodna chahte ho. Ya ghataana. Ya guna. Ya bhaag.

Python ko aap “words” me nahi bolte.
Python ko aap symbols se batate ho.

In symbols ko hi kehte hain operators.

HOW: 4 basic math operators

Python me basic math ke liye 4 sabse common operators:

+ Addition (jodna)
- Subtraction (ghataana)
* Multiplication (guna karna)
/ Division (bhaag karna)

Bas. Itna hi.

Ek important baat (Division wali)

Division (/) ka answer aksar decimal me aata hai.
Even agar answer “2” lag raha ho, Python usko 2.0 bhi bana sakta hai.
Matlab division ka result aksar float hota hai.

Analogy

+ (add) : 2 aloo + 3 aloo = 5 aloo
- (Subtract): 5 biscuit – 2 biscuit = 3 biscuit
* (Multiply) : 4 din * 2 class = 8 class
/ (Divide): 10 roti / 4 log = 2.5 roti per person (decimal aa sakta hai)

Example

Hum 2 numbers lete hain aur unpe 4 operations karte hain.
Aap Windows me IDLE khol kar run kar sakte ho.

# Lesson 10: Basic Math Operators

x = 10
y = 3

print("x + y =", x + y)
print("x - y =", x - y)
print("x * y =", x * y)
print("x / y =", x / y)

Try It Yourself

User se 2 numbers lo.
Dono ko int() me convert karo.
Inka sum aur product print karo.

# Lesson 10: Input se 2 numbers lo, phir sum aur product nikaalo

a_text = input("Enter first number: ")
b_text = input("Enter second number: ")

a = int(a_text)
b = int(b_text)

print("Sum =", a + b)
print("Product =", a * b)

Summary

Python me basic math operators: + - * /
Division (/) ka answer decimal (float) ho sakta hai
Variables me numbers rakh kar aap easy calculations kar sakte ho

# Lesson 10: Division aksar float deta hai

print(8 / 4)   # 2.0
print(9 / 4)   # 2.25

Next hum “comparison” seekhenge: > < == (bada, chhota, barabar).
