- 1. Whole Numbers Add with Ease 08/14/13 1
- 2. Addition of two digit numbers 08/14/13 2
- 3. Adding two digit numbers orally is difficult for children of the primary classes. All children make mistakes while adding mentally and lose marks. In this tutorial I have tried to simplify addition of two digit numbers and I have also given some exercise problems to solve on their own. If addition sums are practiced repeatedly in this way errors can be minimized to a large extent. This method is easy and quick. The carry over is always 1. Enjoy learning this new and easy method of addition. I wish you happy math learning…. Best Wishes. Kausalya Janardanan 13/08/2013 kayjayr@gmail.com 08/14/13 3
- 4. Add the following numbers: Sum No.1. 08/14/13 4 53+ 42 65 86 94 340 Method: Step1: The normal method is to add the first row of numbers 4+6+5+2+3=20 Step2: 2 is carried to the second row. Step3: Add 9+8+6+4+5+2 =34(2 is the number carried while adding the first row of numbers)
- 5. 08/14/13 5 The Easier Method is as follows: Sum No.1. 1 1 53+ 42 1 65 1 1 86 94 340 Method: First column addition: Step1: Add 6+4=10. Remember 0 and put 1 on the top of 6. Step2: Add 5+2+3=10 put 1 on top of 3 and write 0 in the answer. Second column addition: Step3:Add 9+8=17. Put 1 on the top of 8 and add 7 and 6. Step4: Now (7+6)=13. Step5: Put 1 on the top of 6 and add 3to (4+5)=12. Put 1 on the top of the number 5. Step6:In the first column addition there are two ones (1)written on the top of 6 &3. Step7: These ones (1) should be added (1+1=2). Step8: They are carried to the second column addition. Step9:Refer step 5. Add 2+12=14. Write 4 in the answer to the left of zero. Step10: Three ones (1) are written on the top of three numbers in the second row. Add them and write 3 to the left of 4. So the answer is 340 for the given sum.

- 7. 08/14/13 7 Addition of Three Digit Numbers 3 5 4 4 51 91 91 81 71 2 9 8 20 9 8 Three digit addition is carried out in the same way. The number of digits carried in the First coloumn is 2. The number of digits carried in the second coloumn is also 2. In the third coloumn, 9+2=11, 1 is written on the top of 9, 1+4+3=8, 8+2(carried over digit)=10. Put Zero in the answer to the left of 9 1+1=2; put it to the left of zero in the answer. Hence the answer 2098.
- 8. 08/14/13 8 71 81 91 41 3 2 5 3 5 31 61 71 41 7 3 81 91 81 51 7 7 3 (+1) 9 1 Addition of Four Digit Numbers 38 5 0 0 Answer the following questions: 1.The number carried to the second column from the first column is--------. 2. The sum of the digits in the second column and the digit carried from the first column is ------ 3.The number carried to the fourth column of digits is ------- 4. Why (+1) is written in the third column of digits below 3, the last digit? 5. Verify the answer by adding in the normal method.
- 9. 08/14/13 9 Practice the following sums 4 3 9 6 5 1 5 3 4 9 2 8 7 3 6 5 8 7 2 4 9 8 4 3 7 6 3 5 7 0 Find the answer to the sum in the same method. Verify the answer by the normal method. Sum no. 1
- 10. 08/14/13 10 7 9 9 * 2 * 1 6 2 4 * 7 6 5 8 24 3 1 Sum no.2 Answer is given. Find the Stars
