FAQs on Addition with place value Video Lecture - Class 3

1. What is addition with place value in mathematics?
Ans. Addition with place value is a mathematical concept where numbers are added by considering the value of each digit in its respective place. For example, in the number 456, the digit 4 represents 400, the digit 5 represents 50, and the digit 6 represents 6. By adding these place values, we can find the sum of the numbers.
2. How does addition with place value work?
Ans. Addition with place value works by adding the digits in each place value column. Start from the rightmost column and add the digits vertically, carrying over any excess to the next column. Repeat this process until all columns have been added. This method ensures that the correct sum is obtained by considering the place value of each digit.
3. Can you explain how to add two numbers using place value?
Ans. Sure! To add two numbers using place value, align them vertically with their corresponding digits in each place value column. Start adding from the rightmost column and move leftward. Add the digits in each column, carrying over any excess to the next column if necessary. Continue this process until all columns have been added, and you will obtain the sum of the two numbers.
4. What is the significance of place value in addition?
Ans. Place value is significant in addition as it determines the value of each digit in a number. By considering the place value, we can correctly add the digits in each column, ensuring that the sum is accurate. Without place value, addition would be ambiguous, and the calculation would not reflect the true value of the numbers being added.
5. Can you provide an example of addition with place value?
Ans. Certainly! Let's add the numbers 347 and 582 using place value. Aligning them vertically, we start from the rightmost column: 347 + 582 _____ 9 (in the ones place) 8 (in the tens place) 3 (in the hundreds place) _____ 929 Therefore, the sum of 347 and 582 is 929, obtained by adding the digits in each place value column.
