236 Appendix A: RPN and the Stack Keystrokes (RPN mode) Display 84000 § § § 84,000. 168,000.00 336,000.00 672,000.00 Enters base amount into displayed X-register. Annual sales after first year. Annual sales after second year. Annual sales after third year. In the example above, the constant was repeatedly multiplied by the result of the previous operation, which was already in the displayed X-register. In another class of calculations with constants, the constant is multiplied by (or added to, etc.) a new number keyed into the displayed X-register. For these calculations, you must press O before keying in a new number after having pressed an operator key. If this were not done, the stack would lift when you keyed in a new number after pressing the operator key, and the Y-register would no longer contain the constant. (Recall - from page 230 - that the stack does not lift when a number is keyed into the displayed X-register after O is pressed.) Example: At Permex Pipes a certain pipe fitting is packaged in quantities of 15, 75, and 250. If the cost per fitting is $4.38, calculate the cost of each package.* Keystrokes (RPN mode) Display 4.38\\ \ 15 § O75 § O250 § 4.38 15. 65.70 75. 328.50 250. 1,095.00 Enters constant into Y-, Z-, and T-registers. Enters first quantity into displayed X-register. Cost of a package of 15. Clears display and enters second quantity into displayed X-register. Cost of a package of 75. Clears display and enters third quantity into displayed X-register. Cost of a package of 250. * You may want to compare this method of arithmetic calculations with constants to the method using F described on page 91.
