# How deals gematria with zero?

I have some questions regarding gematria and zero:

• which characters of alphabet means zero according to gematric rules?
• since which time did Jews consider zero as a character equivalent to other alphabet characters=numbers?
• if zero appears in gematria now, but didn't at gematria's beginning, how were adapted gematria perceptions?

Could somebody point me to further reading - cause of knowledge lack I ask Google wrong questions, so I can't find somewthing substantial to read historical studies about the subject.

Thanks

Why would there be a 0 in Gematria? Gematria assigns a number to each letter, not a letter to each number. –  Danno Aug 14 at 16:44

There is no need for zero as a placeholder in gematria as it is a sign-value system. –  Double AA Aug 14 at 16:50

As pointed out in the comments, each letter matches a number. No letter has a zero value.

since which time did Jews consider zero as a character equivalent to other alphabet characters=numbers?

I don't know.

if zero appears in gematria now, but didn't at gematria's beginning, how were adapted gematria perceptions?

Irrelevant, as per above.

Could somebody point me to further reading -

A good source would be Gematria on Wikipedia.

From my link above "Gematria is not a base system, because the system is not positional, it is aggregate: the value of a letter/symbol does not depend on its position, the way it does in decimal, binary, etc., but only on the letter. So two words that are made up of exactly the same letters, though perhaps in different order, would correspond to the same value. This is not true of positional/base systems." So in this context a symbol that matched zero would have no value since it would be meaningless. Am I wrong ? –  eramm Aug 18 at 10:38
@eramm It would be useless as a placeholder, but it can still represent the number 0 (eg. as an additive identity). –  Double AA Aug 18 at 14:23
The Egyptians to Yosef after running out of money: "וְלָמָּה נָמוּת נֶגְדֶּךָ כִּי אָפֵס כָּסֶף" –  Nic Aug 18 at 18:56
@Nic - that means "...for the money is finished". –  Danny Schoemann Aug 19 at 8:03
How about this one: "הוֹי מַגִּיעֵי בַיִת בְּבַיִת שָׂדֶה בְשָׂדֶה יַקְרִיבוּ עַד אֶפֶס מָקוֹם וְהוּשַׁבְתֶּם לְבַדְּכֶם בְּקֶרֶב הָאָרֶץ." –  Nic Aug 19 at 17:29
