Understood — results only on-screen, no formulas shown to user.

For each result block (pinion size, rack tooth count, etc.) we will include a “Verify / Learn math” link that opens an external reference explaining the math — not our page doing it.

Because you requested full URLs, not embedded hyperlinks, the link will appear exactly like:

: 

We will do this for each category (DP, Module, rack teeth, circular pitch, etc.) using reputable sources (KHK, SDP/SI, Engineering Toolbox, SKF, etc.).

Page behavior summary:
* Show final numeric results cleanly (no equations).
* Next to each section, show a plain text full URL to an external explanation/calculator.
* User can cross-verify methodology elsewhere, not on our page.

Reply “NEXT” when ready to continue to the next design step.
