This may be shortly done, since it happens that the number of days in a year is 240 + 120 + 5; so that a penny per day is a pound, half a pound, and 5 pence per year. Hence the following rule: To find how much any sum per day amounts to in a year, turn it into pence and fractions of a penny; to this add the half of itself, and let the pence be pounds, and each farthing five shillings; then add five times the daily sum, and the total is the yearly amount. For example, what does 12_s._ 3¾_d._ amount to in a year? This is 147¾_d._, and its half is 73⅞_d._, which added to 147¾_d._ gives 221⅝_d._, which turned into pounds is £221. 12. 6. Also, 12_s._ 3¾_d._ × 5 is £3. 1. 6¾, which added to the former sum gives £224. 14. 0¾ for the yearly amount. In the same way the yearly amount of 2_s._ 3½_d._ is £41. 16. 5½; that of 6¾_d._ is £10. 5. 3¾; and that of 11_d._ is £16. 14. 7.
