FAQs on Tricks for Multiplication & Few Examples: Vedic Mathematics Video Lecture - IBPS PO Prelims & Mains Preparation - Bank Exams

1. What are some effective tricks for multiplying two-digit numbers using Vedic Mathematics?
Ans. One effective trick is the "Nikhilam Sutra," which involves taking the base (like 10, 100, etc.) and finding how far each number is from that base. For example, to multiply 98 by 97, you can see that 98 is 2 less than 100 and 97 is 3 less than 100. The product can be calculated as (100 - (2 + 3)) and then subtracting the product of the differences (2*3). Thus, 98*97 = 9506.
2. How can I use Vedic Mathematics to multiply numbers close to base 10 efficiently?
Ans. When multiplying numbers close to 10, you can use the "Urdhva-Tiryagbhyam Sutra." For instance, to calculate 9 and 8, you can subtract each number from 10 (9 becomes 1 and 8 becomes 2). Then, subtract the sum of these differences from the base (10 - (1 + 2) = 7). Finally, multiply the differences (1*2 = 2). So, 9*8 = 72.
3. What is the role of base numbers in Vedic Mathematics multiplication techniques?
Ans. Base numbers are crucial in Vedic Mathematics as they simplify calculations by reducing the numbers into manageable differences. For example, using a base of 100 for numbers like 97 and 98 allows you to work with smaller digits (3 and 2) and utilize simple arithmetic operations, making multiplication quicker and easier.
4. Can Vedic Mathematics techniques be applied to larger numbers for bank exams?
Ans. Yes, Vedic Mathematics techniques can be scaled to larger numbers. You can break down larger numbers into parts that are easier to manage. For instance, for multiplying 123 by 45, you can split it into (100 + 20 + 3) and (40 + 5) and apply distributive properties to simplify the calculation into smaller, more manageable parts.
5. What are the benefits of learning Vedic Mathematics for bank exam preparation?
Ans. Learning Vedic Mathematics can significantly enhance speed and accuracy in calculations, which is crucial for bank exams. The techniques reduce the time taken for solving arithmetic problems, allowing more time for complex questions. Additionally, they build confidence in dealing with numbers, making exam preparation more effective.
