FAQ (frequently asked questions)

Do I have to sign up?

No. The primary advantage of creating an account is that the Solver’s contents can be saved as worksheets, which you can continue working on at any time.

If you’re not signed in, there is no way for us to tell who you are and what formulas you’ve worked on in the past.

Can I add my own formulas?

Yes - click the “Create formulas” link up at the top of the page.

We refer to any formulas created here as private formulas. You can search for and view them via the normal search engine - check the “Private formula” box in the left-hand column to see (only) these formulas.

Note if you’re not logged in, all private formulas will be lost when your browser session ends.
