    Hi Aarin,

    Thank you for taking the time to write suggestions.

    1. I didn’t quite understand the first suggestion. Are you saying we teach to calculate from right to left in Chapter 8?

    2. For the second point on including percentages, fractions etc, I will add it to my backlog and will work to incorporate it into the book and course. I have purposely kept some of the more complicated stuff out of the book so that it remains relevant to most people reading the book or watching the course. I will try to create a course companion so that it becomes useful.

    3 & 4. For the next two points which are sort of interlinked which is to remember numbers in your head and carrying over numbers, I would encourage you to read this community post – https://ofpad.com/topic/is-only-the-calculation-performed-in-the-mind/
    It probably has the exact answer that you are looking for. Let me know if it doesn’t answer the question.

    5. Remembering to calculate from left to right comes with practice. If you do it enough number of times, it will become the only natural way to do mental math.

    6. The only way to be 100% sure is to of course do the math problem again. Both methods rely on estimation and has an accuracy of >90%. Using both methods together will increase the accuracy even further because the chances of both methods not catching it combined is pretty slim. If I find a method that has even more accuracy, I will make sure I include it.

    Let me know if this answers all your questions. If you do enjoy the book, please don’t forget to leave a review. It is really helpful to reach more students.

    Hey Honorous,

    Glad you were able to figure it out.

    No question is a bad question.

    I will just highlight the steps here in case it will help other students get clarity.

    We are dividing 47 / 12

    12 x 3 = 36

    So 3 is the quotient.

    47 – 36 = 11

    11 is the reminder.

    If you wanted to calculate decimal places you would add 0 to 11 and continue dividing by adding a decimal point. But since we are interested in getting the reminder we won’t do that.

    Hope this clarifies. Feel free to ask anything that you need help with.

    Hey Faruuq,

    Digit sum can only verify your answer with 90% accuracy.

    If you want a higher level of accuracy you can use the DS method in conjunction with the DD method. However even that is not 100%.

    The only way to be 100% sure your answer is correct, is to do the calculation again.

    Hope this clarifies.

    Hi Areadien,

    If you insist on using the Stem Method, then the best stem number to use is 20.

    However, unless you are practising stem multiplication, you should be using the LR method to do the multiplication of 35 x 5.

    With the LR method, it is only 3 simple steps:
    1) 3 x 5 = 15
    2) 5 x 5 = 25
    3) Putting it together we get 175.

    Hi Areadien,

    Yes, you are right. Both methods are not 100%. They are meant to check your answer with a reasonable level of accuracy but there will always be cases where they don’t catch the error.

    Hi Areadien,

    The easiest way is to use the Bridge or the Vitruvian Man method. But yes, the longer the problem the harder it is going to be do it.

    Hi Adreadien,

    In this case you will retain the -1 as -1 instead of adding 11 to make it positive. Here is how that will turn out:

    Addition
    Check: 14 + 10 = 24
    DD: 3 – 1 = 2

    Subtraction
    Check: 14 – 10 = 4
    DD: 3 – -1 = 4
    DD: 3 + 1 = 4

    Multiplication
    Check: 14 * 10 = 140
    DD: 3 * -1 = (0+1) – 4
    DD: -3 = -3

    Division
    Check: 14 / 10 = 1.4
    DD: 3 / -1 = 1 – 4
    DD: 3 / -1 = -3
    DD: 3 = -3 * -1

    I will add this scenario to the content during the next update.

    Let me know if this answer clarifies your question.

    Hi Areadien,

    As far as I know, there is no scenario where the DD method will fail where the DS method succeeds.

    The DD method is more accurate than DS Method. You can be sure 90% of the time with the DS method. However, with the DD method, you will have more than 95% certain.

    We still cover the DS method because it is a lot faster to do than the DD method.

    Hi Mohammad,

    Welcome to the forum. I am guessing the lie is you met Princess Diana. 😉

    What habit do you want to focus on first?
