Chapter 10: Integers par Kriyaayein
Hum integers jodna-ghataana jaante hain. Is chapter mein paheliyon, carrom ki goti aur tokens se dohraayenge, phir integers ka guna-bhaag seekhenge: do negative positive kyun banaate hain, Brahmagupta ke chinh niyam, aur adla-badli, grouping aur baantne ke gun kaise chalte hain.
Is chapter mein tum
- chaalon aur tokens se integers jodna-ghataana
- integers ka guna aur chinh niyam samjhaana
- integers ka bhaag
- sawaalon mein integer kriyaaon ke gun lagaana
Topics
- Integers ka Jaldi Dohraav NCERT P2 2.1
Integers maap aur disha dono batate hain; a aur b chaal ke baad sthaan a + b.
- Integers ka Multiplication NCERT P2 2.2
Ek jaise chinh: positive guna-phal; alag chinh: negative.
- Integers ka Division NCERT P2 2.2
Bhaag mein guna jaise hi chinh niyam.
Key words
- Integer
- poorn sankhya, positive, negative ya zero
- Additive inverse
- jo jodkar 0 de: a ke liye −a
- Zero pair
- ek + aur ek − token saath
- Multiplier
- jo batata hai kitni baar
- Commutative
- kram badal sakte hain: a × b = b × a
- Distributive
- a × (b + c) = a × b + a × c
Summary
- Ghataana inverse jodna: 4 − (−12) = 16.
- Ek jaise chinh ka guna positive, alag ka negative.
- Bhaag mein wahi niyam: (−100) ÷ (−4) = 25.
- Integer guna commutative, associative aur jod par distributive hai.
