“Calculating Traditional Root Sums”

If you have purchased either the 999 Wednesday’s Sun Pick 3 Strategy or our “Play 7-15 Weekly Pair Stretch Chart“, you will need to know how to calculate a root sum.

The instructions are noted below.

Root Sums

In the simplest terms, finding the root sum of a combination involves reducing its sum down to a single digit.

For example, the root sum of “59872” is 4.

You get this by adding all digits of the number / combination together:

5+9+8+7+2=31 and 3+1=4.

You will note that the first sum of the digits added together was 31, but because this is not a single digit, we had to take the additional step by adding those two digits together to get down to a single digit–and to what is called the “root” sum.

Finding Traditional Root Sums

Let us find the sum of these five (5) Pick 3 combinations, and then take it to its single-digit root sum:

429=4+2+9=15 and 1+5=6. 6 is the root sum of 429

837=8+3+7=18, and 1+8=9. 9 is the root sum of 837

063=0+6+3=9. 9 is the root sum of 063 (since the first sum is already a single digit, we stop there).

482=4+8+2=14 and 1+4=5. 5 is the root sum of 482

236=2+3+6=2. 2 is the root sum of 236

**SBIP999 Tip: **

A simple way to finding root sums is to isolate/forget about any digits that add up to nine (9). For example, in the 2**36** example, we can easily see that 3+6 equals 9, so we know the root sum is 2. Same deal with the 42**9**: when we discard the 9, we know the root sum is 6. This holds true except in an example like 0**63** where you would not forget about the nine because that is the total sum.

Last example: 5**9**8**72–**in this combination, when we take out the 9 and the 72 (because it equals 9), we can easily add up the 5 plus 8 to get our root sum of 4 (5+8=13 and 1+3=4)
