Numerology Calculation – The Pythagorean Method


In this post, I would like to show you how you can perform your own numerology calculation via the Pythagorean method. It is really easy to do and all you need is a pen /pencil and paper. You can become a master in no time! But the harder part, of course, is how to interpret the numbers.

Setting Up That Inverted Triangle!

The first thing that you need to do is to draw an inverted triangle and a few dividing lines in between, as shown below.

This is where you will eventually put in your date of birth and calculate your numbers representing your inner and outer character.

Character Numerology Calculation

To calculate your Character Numerology numbers, write down your date of birth as shown below. Let’s use the date of birth 16 September 1923 in the example and you can input yours and calculate too as we go along.

Numerology Calculation - Inner Character Calculation Step 1

As shown above, sum the:

Day: 1 + 6 = 7
Month: 0 + 9 = 9
Year: 1 + 9 = 10; 1 + 0 = 1
Year: 2 + 3 = 5

The next step is to further reduce the number to single digits until you get into your Character Root Number as shown below.

The calculation is as follows:

2nd line left side: 7 + 9 = 16; 1 + 6 = 7
2nd line right side: 1 + 5 = 6
3rd line (Character Root Number): 7 + 6 = 13; 1 + 3 = 4
With the above, you now have your numbers representing your inner character.

We can now move on to calculate the numbers for your outer character. This is as shown below.

By the coloured lines, below shows the formula:

Orange (Left): 9 + 7 = 16; 1 + 6 = 7
Blue (Left): 7 + 7 = 14; 1 + 4 = 5
Total: 7 + 5 = 12; 1 + 2 = 3

Orange (Right): 1 + 6 = 7
Blue (Right) = 5 + 6 = 11; 1 + 1 = 2
Total: 7 + 2 = 9

Green: 6 + 4 = 10; 1 + 0 = 1
Red: 7 + 4 = 11; 1 + 1 = 2
Purple: 1 + 2 = 3

Congratulations! You now know how to calculate your Character Numerology Numbers! In case you are facing some difficulty in your calculation, you are more than welcome to reach out to me.

Inner Character

Having learned how to calculate your Character Numerology Numbers, let’s take a look at the numbers revealing your inner character. These are the numbers within the inverted triangle. Using the example earlier for illustration, the numbers are:

Numerology Calculation - Inner Character

There are multiple ways/combinations to read the numbers that can draw insights on your inner character. The most common one is your Character Root Number. In this example, the Character Root Number is ‘4’. Number ‘4’ represents that he has the trait of having great planning skills, is smart, well-educated, and admires beauty. On a negative side, there can be a tendency that he may be an over perfectionist that may cause him to lose his direction.

You will also notice 7-6-4. It describes that he has great observation, is trustworthy, gains support from the people, and has good management and negotiation skills. This is also reinforced by the 7-9 on the top left which also explains that he has many supporters to assist him in his career. His 1-5 in the top right explains that he is a man of principle and can be quite stubborn. It can work both positively and negatively.

There is much more that we can examine from these numbers but I think it is sufficient to say that a person with such numbers generally has a good life and is in control of his life.

Outer Character

We can now move on to study the numbers revealing the outer character. The outer character numbers generally refer to how people see you. It can be different right? How you see yourself versus how people see you. and the latter is often something you won’t get feedback on? The outer character numbers may provide you a viewpoint on that, which, you can see it also as something that you portray to others, knowingly or unknowingly. So if the numbers may reveal something negative, you can’t change it. But, this is exactly where you can then work on it to change yourself consciously. Make sense?

Numerology Calculation - Outer Character

So let’s take a look at some examples above. You will notice there is a 1-2. And this means that the person carries authority when he speaks, but he is unaware that there can be people talking bad about him behind his back. So perhaps if he feels that too in reality, that he feels it is a problem, then that is something he may want to consider working on. Perhaps he can learn to tone down the way he speaks for example. But on the other hand, he can choose to ignore it if he thinks it doesn’t matter. And this can be perfectly valid anyway because there can be other factors negating this.

Character Root Numbers

The Character Root Number defines your core characteristic. It gives a view of what kind of person you are. But as you might have guessed or seen above, it is not everything as there can be so much more to analyze about your other numbers or someone else that you know. Nevertheless, the Character Root Number is the core number.

There are in total 9 of them which I will give a quick general positive and negative view in simple terms to give you a flavour what do they mean:

     1 Leader – Self-Centred
     2 Communicator – Talkative
     3 Enthusiast – Temperamental
     4 Planner / Well-organised – Overly Perfectionist
     5 Ambitious – Obstinate
     6 Wealthy – Materialistic
     7 Popular – Snobbish
     8 Responsible – Stressful
     9 Entrepreneur – Lazy

Lastly, and it may sound odd to you, but I just want to say that when we perform calculation, especially when you are doing it on/for someone else, we should have the mentality that we are doing this with good intention. Do good deeds and cultivate good thoughts.

Feel free to leave me a comment or question and I will try to answer you as best as I can!
