There is no letter group for 9 in the commonly published Chaldean chart. The value is traditionally treated as set apart, but it remains a valid reduced result. For example, a total of 18 becomes root 9.
How names are handled
Capitalization does not affect a result. Common accented Latin characters are normalized to their base letter, so É uses E and Ñ uses N. Spaces, hyphens, apostrophes, periods, and ordinary punctuation add nothing, although the calculator keeps word boundaries so it can show useful subtotals.
The chart does not define Arabic, Urdu, Devanagari, Chinese, Cyrillic, or other writing systems. Automated transliteration can change spelling choices that matter to a letter total, so the calculator asks you to enter the usual Latin transliteration you personally use.
Worked examples
ALICE
A1 + L3 + I1 + C3 + E5 = 13. Then 1 + 3 = 4, displayed as 13/4.
JOHN
J1 + O7 + H5 + N5 = 18. Then 1 + 8 = 9, displayed as 18/9.
CHALDEAN NUMEROLOGY
The word subtotals are 30 and 40. Together they make 70, which reduces to 7 and is displayed as 70/7.
A compound should be preserved before reduction. This calculator does not stop at 11, 22, or 33 because that master-number rule belongs to other modern approaches unless explicitly stated.
