Square numbers ki suchi dekhkar lagta hai, jaise ye alag-alag tathya hain jinhen yaad karke bhi aap bhool jayenge. Farsh par tiles ka ek chaukor hissa sochiye: jitni panktiyan, utne hi columns, aur har pankti mein utni hi tiles. Yahi square number hai - kisi sankhya ko usi se guna karna, yani n x n. Ek tile, 1x1=1. Do panktiyan aur do columns, 2x2=4; phir ek nai pankti aur column joden, to 3x3=9. Ab dhyan dijiye: 1 se 4 tak teen tiles juri, aur 4 se 9 tak paanch. Yahi mod hai. Square numbers random facts nahin; har naya chaukor pichhle wale mein agli odd number jodkar banta hai. Is pattern se 1 se 10 tak chaliye: 1, phir +3=4, +5=9, +7=16, +9=25, +11=36, +13=49, +15=64, +17=81, aur +19=100. Yani 10x10=100. Koi square bhool jaen, to pichhle chaukor mein agli odd number jitni tiles joden. Bas - yah yaad karne ki suchi nahin, badhta hua pattern hai.
