★ SAAVI इसे ऐसे पढ़ाती है:Dekho — tumhare papa ya mummy jab dukaan pe samaan khareedne jaate hain na — tab dukaan mein paison ka hisaab kaise rakha jaata hai, socho zara? Agar dukaan ko ₹500 ka fayda hua, toh wo +500 hai. Aur agar kisi din dukaan ko ₹200 ka nuksaan ho gaya, toh wo -200 hai. Ye +500 aur -200 hi toh Integers hain!
❌ Ek bahut common galti jo tum karti ho, wo ye hai ki kai baar tum sochti ho ki -10, -5 se bada hai, kyunki 10 toh 5 se bada hota hai na?
✅ Lekin asal mein aisa nahi hota. Integers ko number line par dekho. Jo number number line par right side mein hota hai, wo bada hota hai. Aur jo left side mein hota hai, wo chhota hota hai. Toh -5, -10 se right mein hai, isliye -5 bada hai!
Ek kaam karo — ghar mein kuch laal bindi (bindi ke packet se) aur kuch neele bindi le lo. Har laal bindi ko +1 maano aur har neeli bindi ko -1. Jab bhi ek laal aur ek neeli bindi ek saath ho, toh socho ki wo ek doosre ko cancel kar dete hain (zero ban jaate hain). Ab '5 + (-3)' solve karne ke liye 5 laal bindi aur 3 neeli bindi lo — dekho kya bachta hai!

★ SAAVI इसे ऐसे पढ़ाती है:Dekho — tumhari Mummy jab halwa banati hain, toh kabhi-kabhi woh kehti hain, 'Aaj main sirf aadha (1/2) cup sooji use karungi.' Ab agar recipe mein 1 cup sooji ka ek chauthaai (1/4) ghee daalne ko kaha hai, toh socho zara — jab Mummy sirf aadha cup sooji use karengi, toh ghee bhi 'aadha cup sooji ke 1/4' ke hisaab se daalengi na? Toh us hisaab se, Mummy kitna ghee daalengi?
❌ Kai baar tum sochte ho ki 0.50 aur 0.9 mein se 0.50 bada hai, kyunki 'pachaas' 'nau' se bada lagta hai na?
✅ Lekin beta, decimal numbers ko compare karte waqt humein unki place value dekhni hoti hai. 0.9 ko hum 0.90 bhi likh sakte hain, toh ab batao — 0.50 aur 0.90 mein se kaun bada hai? Har digit ki position dekho, units place, tenths place, hundredths place.
Ek kaam karo — ek square ya rectangle paper lo. Usko beech se fold karke aadhe-aadhe hisson mein baant do, phir dobara fold karke aur chhote hisse banao. Dekho, har fold ke saath kitne parts ban rahe hain aur har part poore paper ka kitna fraction hai?
