I will research and update the course Imran. Thank you for the support.

So say we want to round 7423 up to 10,000. The amount you rounded up by is 2577. Below is the breakdown of the steps.

7 + 2 = 9

4 + 5 = 9

2 + 7 = 9

3 + 7 = 10

The first digits in the above addition 7,4,2,3 are the digits of the original number (7423).

The second digits in the above addition 2,5,7,7 is the amount you have rounded up by (2577).

If instead you want to round up to 8000 instead of 10,000 you dont do the first addition. (7+2 =9). So the amount you rounded up by will be 577 (the last three digits of 2577 when we rounded up to 10.000)

Please let me know if this clarifies.

Hi Susan,

I am guessing you are referring to the 14th problem – 5459 x 11

These are the exact steps

Step 1 – First digit is placed as left hand number of the answer. 

5459 x 11 = 5_ _ _ _ (5 is the first digit)

Step 2 – Each successive digit added to its neighbor the left.

Step 2.A) 5 + 4 = 9

5459 x 11 = 59_ _ _

Step 2.B) 4 + 5 = 9

5459 x 11 = 599_ _

Step 2.C) 5 + 9 = 14

5459 x 11 = 6004_ (Note 1 in 14 is carried over)

Step 3 – Last digit becomes last number of the answer.

5459 x 11 = 60049

The reason why you are getting 59049 is because you are not carrying over the 1 completely across all three digits (599 in this case). When you need to carry over across multiple digits, visualize adding 1 to multiple digits like 599, instead of adding to a single digit 9. When you do that you only have to mentally carry over the number once, instead of carrying over the number 3 times across each individual digit.

Hope this breakdown of the steps clarifies. Please let me know if you need any further clarification and I will be happy to help.

Thank You Siddhant. It took a really long time to make this course so I hope it is at least a little bit good because of the atrocious amount of time I have put into it making it. I am from Chennai. 🙂
