First let's start with the lingo.
Pairs, most of us of course know what a pair is, for newbies , it is 2 of the 3 numbers
Example 369. you have pairs 36-39-69
Sums, that's all the numbers added together.
Example 357 - 3+5+7 = 15 so 15 is your sum.
There are 28 sums 0-27, you can omit sum 0, since 000 rarely falls, but it does once in 10 years, lol
My chart goes from 1-27, It never changes, I have a printed chart that I lamenated for quick reference.
We have one here, and I'll explain how to find it when I am done posting.
Root sums, that is when you add your sum together, up in our example, 15 is the sum, so 1+5=6
6 is your root sum, there are only 9 root sums, unless you want to bring in the 0 for 000...pffffft.
Last sum digit, in our example sum 15, our last sum digit is 5. Now for last sum digit, there are 10, because sums 10 and 20 end in 0.
For root sums, 10 would be 1 and 20 would be 2.
Now for HHH and LLL, that means High High High or Low Low Low
I do not track these, but you will see HLH OR LLH.
This is telling you the value of numbers, 0-4 are lows 5-9 are highs
So in our example 357, it would read LHH
If you want to track these, that's great, but I don't
Now for EEE and OOO
Even and odd numbers
0-2-4-6-8 all even
1-3-5-7-9 all odd
In our example it would read OOO, Again, I don't track these, but if you do, that's great.
