    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?

    Hey Scott. That’s great to hear.

    The person action object is a bit of an overkill for mental math and might needlessly complicate mental math for you.

    I would love to hear the method that works for you. So if something else is working for you, please do share it here.
