Keep three layers separate
Gematria assigns numerical values to Hebrew letters and combines them into a total for a word or phrase. Jewish writers have used these totals in interpretation, including mystical interpretation. The calculation and the meaning proposed around it are separate claims: arithmetic can be checked without accepting every association.
Use a three-part note: exact Hebrew spelling, named calculation method, and the passage or author that gives an interpretation. If the interpretation is your own, label it as a modern observation. This makes your work clearer and prevents a calculator’s output from seeming like a quotation from an ancient book.

Calculate a short example
In the standard method, חי contains Het, ח, worth 8, and Yod, י, worth 10. The total is 18. The Hebrew word means life, which helps explain the cultural association of chai with eighteen. Preserve the two letters in your note rather than calculating from the Latin letters in “chai.”
For a longer example, שלום gives 300 + 30 + 6 + 40 = 376 using ordinary final-letter values. The final Mem ם counts like מ in this convention. Show the addition before looking for another word with the same total; it is much easier to detect an input mistake at this stage.

Check the convention before the connection
Standard, ordinal and reduced methods use different rules, so one spelling can produce several totals. Some systems also give final forms extended values. A result is incomplete unless its method is named. When two calculations disagree, first compare their letters and conventions instead of inventing an explanation for the difference.
Equal totals do not by themselves establish shared meaning, a legal ruling or a prediction. Chabad’s explanations present gematria within a religious interpretive setting and discuss limits on arbitrary connections. Read the surrounding source before treating a numerical resemblance as significant. A name’s total is not a measure of a person’s worth.

Learn a method, then read an example
Start with the linked explanation of gematria. Follow our comparison of standard, ordinal and reduced values, then calculate one word twice while keeping its spelling fixed. Describe exactly which rule changed. This is a manageable first lesson in method rather than a hunt for impressive coincidences.
Next study a documented cultural example such as chai and eighteen. Write separately what the source says and what question it raises for you. You can use numbers as a prompt for reflection while allowing the text, language and your own choices to retain their proper roles.
