Advanced Calculations and Roman Numerals
This page covers more advanced topics in percentage calculations, including interest rates, and introduces Roman numerals.
The document begins with a detailed explanation of how to calculate interest:
Formula: Interest = (Capital * Rate * Time) / 100
Example: For a capital of 15,000 zł, at a 3% annual interest rate, after 6 months:
Interest = (15,000 * 3 * 6/12) / 100 = 225 zł
The page also explains how to perform calculations with permille (parts per thousand):
Example: 5‰ of 1200 = (5/1000) * 1200 = 6
The final section of the document is dedicated to Roman numerals. It provides a comprehensive list of Roman numeral symbols and their corresponding values:
I - 1, V - 5, X - 10, L - 50, C - 100, D - 500, M - 1000
Highlight: The document also includes less common Roman numeral combinations like IV (4) and XL (40).
The page concludes with an example of how to read complex Roman numerals:
Example: MCDLXXVIII = 1000 + (500 - 100) + 50 + 10 + 10 + (5 + 1 + 1 + 1) = 1478
This comprehensive guide provides students with a solid foundation in advanced mathematical concepts and historical number systems, enhancing their overall mathematical literacy.
