Calculators

The easiest way to implement a calculator is an RPN calculator (enter the numbers first, perform the operation last). You need a last-in-first-out stack (there's a "stack" class in C++, but you can also implement your own using an array or a linked list), and a set of functions that pop the last elements from the stack and push the result (e.g. Add() pops the last 2 values and pushes their addition).
You'll need the math.h library for scientific operations.

That is the correct spelling of "calculator" (math computer).

Adding machines have rounding features, so that answers are rounded to the number of decimal places set by a switch. Typically you set anywhere from 0 to 6 decimal places.

To set the time and date on the Casio PAG40-3V Pathfinder, first, press the "Mode" button until you reach the "Timekeeping Mode." Then, hold down the "Adjust" button until the seconds start to flash. Use the "Light" button to toggle between the settings (seconds, hour, minute, month, day, and year), and the "Search" button to change the values. Once you've made your adjustments, press the "Adjust" button again to save the settings.

Immediate Annuity Calculator

An immediate annuity is a product sold by insurance companies that is designed to provide you with an income stream for life. The income, by definition, is designed to start immediately, although some immediate annuities allow you to defer payments for up to one year. It is very important to remember that once you set up an immediate annuity, you no longer control the money you put in it. Likewise, while the income stream is guaranteed for your lifetime, an untimely death will not result in any money being returned to your estate. This calculator is designed to help you estimate your monthly payments from an immediate annuity.

I'll assume you mean TI-83+, as the TI-83 cannot archive programs. On the TI-83+, archived means that a program, list, equation, picture, or other item is stored in the calculator's Flash memory instead of its RAM. This can be used so that the item does not get erased when the RAM is cleared, or to reclaim free RAM for other programs and files. However, archived items cannot be executed or modified, so they must be unarchived first.
