Basic Maths in Python — + – * /

Intro

Ab tak hum text (strings) ke saath + aur * use kar chuke hain.
Aaj hum numbers ke saath simple maths karenge — bilkul calculator jaisa.
Darr nahi: sirf 1 concept, step-by-step.

Concept Explanation

WHY (Pehle “kyun”)

Programming me numbers ka use har jagah hota hai: marks, score, money, toys count, etc.
Python aapke liye calculations fast aur accurate kar sakta hai—jaise bada multiplication bhi.

HOW (Ab “kaise”)

1) Python ke basic math operators

Python me ye common operators use hote hain:

• + Addition (jodna)
• - Subtraction (ghatana)
• * Multiplication (guna) — * ko asterisk bolte hain
• / Division (bhaag) — division ka answer Python me aksar decimal (float) me aata hai

2) Variables ke saath maths (real coding)

Aap numbers ko variables me rakhkar calculate kar sakte ho.
Example idea: x = 20 aur phir y = x - 10 — Python pehle x ki value use karke result store karta hai.
Iska fayda: agar kal x change ho gaya, to y automatically sahi update ho jayega.

Example

Hum + - * / ka quick demo dekhenge.

print(4 + 5)
print(10 - 5)
print(9 * 6)
print(9 / 4)

---

x = 20
y = x - 10
print(y)

Try It Yourself

1. a = 6 aur b = 3 set karo
2. Inka add, subtract, multiply, divide karke print karo
3. Ek baar division ka output dhyaan se dekho (decimal aa sakta hai)

a = 6
b = 3

print(a + b)
print(a - b)
print(a * b)
print(a / b)

---

Summary (2 lines)

Python me basic maths + - * / operators se hota hai.
Division ka answer aksar float (decimal) hota hai.

Next hum order of operations dekhenge (Python pehle * aur / karta hai).
