Meaning
Mispar Katan Mispari, "the integral reduced number", is the shortest of the Hebrew methods. Take a word's standard value and add its digits, again and again, until one digit is left. Shalom, 376, gives 3 + 7 + 6 = 16 and then 7; truth, emet, 441, gives 9. The method has no letter table of its own: it is the standard count followed by a reduction.
The Hebrew calculators and the reference tables list it among the standard methods; when it first came into use is not established. Our old engine computed exactly this and called it Mispar Katan, which is a different method: Katan reduces every letter before adding, Katan Mispari reduces the total after. The chart has named both correctly since October 2026.
How it is counted
שלום, shalom, "peace": ש 300 + ל 30 + ו 6 + ם 40 = 376 by the standard count; 376 → 16 → 7.
נחש, nachash, "serpent": נ 50 + ח 8 + ש 300 = 358 by the standard count; 358 → 16 → 7.
אמת, emet, "truth": א 1 + מ 40 + ת 400 = 441 by the standard count; 441 → 9.
What a single digit can carry
With only nine possible results, one Hebrew word in nine shares any given value; shalom and nachash both give 7, and so do a great many other words. A method this coarse groups words; it cannot single any out, and the tradition never used it to prove anything. Modern numerology, which reduces everything to one digit, rests on the same arithmetic.
Why the two reductions meet
Reducing each letter and reducing the total do not give the same number, but they always meet after one more step. A number and the sum of its digits leave the same remainder when divided by nine, so shalom's small count, 16, also reduces to 7, and emet's, 9, is already 9. The two methods differ in how far they reduce, not in where they end.

This digital root is what Mispar Katan means.
falseWhat the record shows: The digital root of the standard total is Mispar Katan Mispari. Mispar Katan drops the zeros of each letter first, and can give totals well above 9.
