FAQs on Fun Video: Operation on Large Numbers Video Lecture - Mathematics for Grade 5

1. What are the basic operations on large numbers?
Ans. The basic operations on large numbers include addition, subtraction, multiplication, and division. These operations are performed in a similar way as with smaller numbers, but may require carrying or borrowing digits in case of addition or subtraction, and long multiplication or long division methods for multiplication and division.
2. How can I perform addition of large numbers?
Ans. To perform addition of large numbers, line up the digits based on their place value and add each column from right to left. If the sum of digits in a column is greater than 9, carry the tens digit to the next column. Repeat this process until all columns have been added. This method is called the long addition method.
3. What is the long multiplication method for multiplying large numbers?
Ans. The long multiplication method is used to multiply large numbers. It involves multiplying each digit of one number by each digit of the other number and then adding the products together. This process is repeated for each digit in the numbers, starting from the rightmost digit. The final result is the sum of all the partial products.
4. How can I perform subtraction of large numbers?
Ans. Subtraction of large numbers is similar to addition. Line up the digits based on their place value and subtract each column from right to left. If the digit being subtracted is greater than the corresponding digit in the other number, borrow from the next column. Repeat this process until all columns have been subtracted. This method is called the long subtraction method.
5. What is the long division method for dividing large numbers?
Ans. The long division method is used to divide large numbers. It involves dividing the digits of the dividend (the number being divided) by the divisor (the number dividing the dividend) and finding the quotient and remainder. This process is repeated for each digit in the dividend, starting from the leftmost digit. The final result is the quotient with any remainder.
