TI-83 Plus Value Formula and Mathematical Explanation
The TI-83 Plus Value Calculator employs straightforward arithmetic to derive its key metrics. The goal is to distribute the initial purchase cost across various units of academic utility.
Step-by-Step Derivation:
- Total Estimated Usage Hours: This is calculated by multiplying the average hours used per week (during courses) by the number of academic weeks in a year (typically 36) and then by the expected academic years of use.
Total Usage Hours = Hours Per Week × 36 Weeks/Year × Expected Years - Total Courses Requiring Calculator: This is simply the number of courses per year multiplied by the expected academic years of use.
Total Courses = Courses Per Year × Expected Years - Estimated Cost Per Academic Year: The total purchase price divided by the expected academic years of use. This gives an annual depreciation-like figure.
Cost Per Year = Purchase Price / Expected Years - Cost Per Course: The total purchase price divided by the total number of courses where the calculator will be used.
Cost Per Course = Purchase Price / Total Courses - Cost Per Hour of Use: The total purchase price divided by the total estimated usage hours. This is the most granular measure of value.
Cost Per Hour = Purchase Price / Total Usage Hours
