Hello dosto, aapka mathematics problem with fast tricks me swagat hai. Jaisa ki aapne mere do post multiply tricks in Hindi or multiply tricks in hindi-2me multiply ke tricks pade. Ye post bhi usi k aage ka hai. Post padane k baad kahi bhi koi problem aaye to mujhe comments dekar jarur puche.
Example - 1. 12 * 11=?
Solution -: sabse phale 12 or 11 k liye koi ek aadhar (base) lenge. Aadhar aisa le jo 12 or 11 k pass ka ho.
To aadhar = 10
Aadhar lene k baad 12 aadhar 10 se 2 jada or 11 aadhar 10 se 1 jada hai to ise niche jaisa likha hai vaisa likhe -:
12 + 2
11 + 1
Ab tirchhe - tirche jode jaise 12+1=13 ya 11+1=13 ab 13 ko dayie(left side) taraf 12 or 11 k niche likhe aise
12 + 2
11 + 1
13
Ab right side me jo 2 or 1hai unka guna (multiply ) kare 2 * 1 = 2 ise right side likhe aise-:
12 + 2
11 + 1
13 2
Bas ho gaya 12 * 11 = 132 answer.
Vaise maine batadu ki 11 se ki do anko(two digits number ) ka guna (multiply ) karne k fast tricks par ek post likha hai yaha click kark pade pade.

Ab 15 ko bayie (left hand side) 13 or 15 k niche likhe aise-:
13 + 3
12 + 2
_____________
15
______________
Step-3-: ab 3 or 2 ka guna(multiply) kark 3 or 2 k niche likhe.
13 + 3
12 + 2
____________
15 6
____________
To 13 * 12 = 156 answer.
Example -3 . 18 * 17 = ?
Solution -: step-1-: base =10 , 18 or 17 base 10 se 8 or 7 jada(more) hai.

Yaha 56 do anko ( 2 digits number ) ka hai isliye 6 ko dayie(right side) 8 or 7 k niche likhenge or 5 carry k rup me 15 me plus kardenge.
15 + 5 = 20
18 + 8
17 + 7
