annuoidun

Annuoidun is a term that appears in some older scientific literature, primarily related to the study of annuities and their valuation. It is not a commonly used term in modern financial mathematics or actuarial science. The word itself seems to be a portmanteau, likely combining elements of "annuity" and "due," suggesting a valuation or calculation related to an annuity due. An annuity due is a series of equal payments made at the beginning of each period.

The historical context for "annuoidun" might be found in early texts on life insurance, pensions, or financial planning where specific methods for calculating the present value or future value of such payment streams were being developed. The precise meaning and application of "annuoidun" would depend on the specific text in which it is found, as it may have been a localized or idiosyncratic term used by a particular author or group of researchers. Without a clear modern definition, its interpretation relies on understanding the context of the historical documents it is associated with, focusing on calculations pertaining to payments made at the start of intervals rather than at the end.
