Fast Multiplication trick 4-digit by 2-digit number formula
Aapko ye shortcut multiplication trick achhe se aur fast samjh me aaye isliye humne iss ka formula banaya hai. Formula nichey diya gaya hai-:
Hum jaante hai ki, 4-digit ke number me one place (O₁), tens place (T₁), hundred place (H) aur Thousand place (Th) par number hote hai.
Jaise-: 4213 me one place (O₁) = 3, tens place (T₁) = 1, hundred place (H) = 2 aur Thousand place (Th) = 4
Issi prakar se 2-digit ke number me one place (O₂) aur tens place (T₂) par number hota hai.
Jaise-: 58 me one place (O₂) = 8 aur tens place (T₂) = 5
To iss trick ko nichey diye step se karna hai.
Jaise-: 4213 me one place (O₁) = 3, tens place (T₁) = 1, hundred place (H) = 2 aur Thousand place (Th) = 4
Issi prakar se 2-digit ke number me one place (O₂) aur tens place (T₂) par number hota hai.
Jaise-: 58 me one place (O₂) = 8 aur tens place (T₂) = 5
To iss trick ko nichey diye step se karna hai.
Step-1. (O₁)×(O₂)
Step-2. (O₁)×(T₂)+(T₁)×(O₂)
Step-3. (H)×(O₂)+(T₁)×(T₂)
Step-4. (Th)×(O₂)+(H)×(T₂)
Step-5. (Th)×(T₂)
Aapko kewal formula ko follow karna hai aur aap ye trick achhe se samjh jaayenge.
Ab aap soch rahe honge ki , ye formula Aapkp yaad kaise rahega ? To hum aapko batade ki iss formula ko Aapko yaad karne ki koi jarurat nahi hai. Kewal aap iss formula ke pattern ko samjh karke kam-se-kam 5 question ki practice kar lo to aapko iss formula ki jarurat nahi padegi.
Isliye hum aapse request karte hai ki , aap bhi ek pen and paper lekar humare saath-saath iss shortcut trick ki practice kariye.
To chaliye aapko ek simple sa question lekar iss multiplication shortcut trick sikhate hai.
