 Hello and welcome to the session. In this session we are going to discuss the following question and the question says that First part, find the sum 4,325 plus 3,467 plus 8,746 and second part is find the difference 705 minus 526. Let us start with the solution of the given question. In the first part of the question we have to find the sum. So first we write the number 4,325 and then we write the second number that is 3,467 then the third number 8,746 one below the other lining up the digits at the unit place. Now first we add the digits at unit place that is 5 plus 7 plus 6 and this is equal to 18. Now it is a two digit number so we write 8 at unit place and place 1 above the 10th. Now we add the digits at 10th place that is 1 plus 2 plus 6 plus 4 which is equal to 13. Again it is a two digit number so we place 3 at 10th place and 1 above the 100th. Now we add the digits at 100th place that is 1 plus 3 plus 4 plus 7 and that is equal to 15. Again it is a two digit number so we write 5 at 100th place and place 1 above the 1000th. Now we add the digits at 1000th place 1 plus 4 plus 3 plus 8 and this is equal to 16. So we write 16 and thus we get the sum as 16,538 so we get 4,325 plus 3467 plus 8,746 is equal to 16,538 which is the required answer to the first part of the question. Now we move on to the second part of the question where we have to find the difference that is 705 minus 526 and we know that to subtract whole numbers we first line up the digits and then we subtract the digits in each place value position starting from the unit place. We may need to regroup the digits while subtracting so first we shall line up the digits. First we write larger number that is 705 below it we write 526. Now we start subtracting from units place since number to be subtracted that is 6 is larger than 5 so we rename 5 as 15 and rename 0 at 10th place as 9 and 7 at 100th place as 6. Now at units place we have 15 minus 6 which is equal to 9 so at units place we write 9. Now we subtract the digits at 10th place here we have renamed 0 as 9 so we have 9 minus 2 which is equal to 7 so at 10th place we have 7. Now we subtract digits at 100th place we have renamed 7 as 6 so we have 6 minus 5 which is equal to 1 so at 100th place we have 1. So the obtained difference is 179 so we have got the difference that is 705 minus 526 is equal to 179 which is the required answer to the second part of the question. This completes our session hope you enjoyed this session.
