FAQs on Adding Hundreds, Tens and Ones - Addition and Subtraction within 100, Mathematics Video Lecture - Class 6

1. What is the concept of adding hundreds, tens, and ones in mathematics?
2. How do we add numbers with different place values, such as hundreds, tens, and ones?
Ans. To add numbers with different place values, we first align the numbers vertically according to their place values. We start adding from the rightmost digit (ones place) and carry over any excess value to the next place value. We continue this process until we have added all the digits, ensuring the correct addition of hundreds, tens, and ones.
3. Can you provide an example of adding hundreds, tens, and ones?
Ans. Sure! Let's add 345 and 256. 345 + 256 ------ 601 In this example, we start by adding the ones place: 5 + 6 = 11. We write down 1 and carry over 1 to the tens place. Then, we add the tens place: 4 + 5 + 1 (carried) = 10. We write down 0 and carry over 1 to the hundreds place. Finally, we add the hundreds place: 3 + 2 + 1 (carried) = 6. The result is 601.
4. Can you explain the concept of subtraction within 100?
Ans. Subtraction within 100 involves subtracting numbers less than or equal to 100. Similar to addition, we align the numbers vertically according to their place values. Starting from the rightmost digit (ones place), we subtract the corresponding digits and, if necessary, borrow from the next higher place value. This process continues until all the digits have been subtracted.
5. Could you provide an example of subtraction within 100?
Ans. Certainly! Let's subtract 87 from 100. 100 - 87 ------- 13 In this example, we start by subtracting the ones place: 0 - 7 is not possible, so we borrow 1 from the tens place. This becomes 10 - 7 = 3. Then, we subtract the tens place: 9 - 8 = 1. Finally, we subtract the hundreds place (which is zero in this case). The result is 13.
