The process of adding the digits of a result again until a stated endpoint is reached. Numerology usually uses a base number, with some methods retaining master numbers.
An example
38 first becomes 3 + 8 = 11. Without an exception, 1 + 1 then gives 2. An explicit master number rule may stop the process earlier.

Digit sum refers to one addition. Reduction describes the repeated procedure and its stopping rule. The distinction helps explain differences between calculators.
Calculation and method
Use the day, month, and full birth year. For April 12, 1990, the digits add up to 1 + 2 + 0 + 4 + 1 + 9 + 9 + 0 = 26. Then 2 + 6 = 8. This example illustrates basic reduction. Master number cases also depend on the stated stopping rule.
