* This equation may be established as follows:—The yearly interest of £1 being £i, it is obvious that £1 is equal in value to an annuity of £ i for any term and an assurance of 1 + i at the end of that term: so £1 is equal in value to a temporary annuity of £i on the life of y, together with a temporary assurance of 1 + ion y, together with an endowment of £1 at end of t years if y is then alive; which is exactly what is expressed by the equation in question.
