Total Debt Ratio = (Total Assets – Total Equity)/Total Assets = 53,274,000/108,615,000 = 0.49 Times
Debt-Equity Ratio = Total debt/Total equity = 53,274,000)/ 55,341,000 = 0.96 Times
Equity Multiplier = Total assets/Total equity = 108,615,000/55,341,000 = 1.96 Times
Interest Coverage = EBIT/Interest = 23,946,000/3,009,000= 7.96 Times
Profit Margin = Net income/Sales = 12,562,200/167,310,000 = 7.51%
Return on Assets = Net income/Total assets = 12,562,200/108,615,000 = 11.57%
Return On Equity = Net income/Total equity = 12,562,200/55,341,000 = 22.70%
Chapter six is a short chapter and it is the final chapter on Greek mathematics. The four main character of this chapter are Nicomachus, Diophantus, Pappus and Hypatia. They all had their own agendas and their own way of contributing to their culture. Nicomachus is renowned for his works The Introduction to Arithmetic and The Introduction to Harmonics. Diophantus famous work was Arithetica, which primarily dealt with algebraic equations. Another famous work of the time was the Collection by Pappus. In this work he covered a wide spectrum of mathematical branches, such as doubling a cube, geometry, polygons and several other topics. Hypatia is most famous for being the first well-documented and eminent woman in Greek mathematics. The wisdom of the mathematicians of this culture no longer surprises me because now I, in a way, expect them to be extremely intelligent. I have learned from previous chapters how heavily the government funded mathematical research and I now know how important the various branches of mathematics were to their society (that is until the spiritual re-birthing of the Roman Empire). I now expect the attempts to square cubes, the marvelous works in geometry, and other such dissection of varies domains of mathematics while reading the chapters. Nonetheless, Diophantus stands out to me because he was the first to use “variables”. I always liked algebra; it is like a big puzzle that I enjoy putting together. Therefore, he is good with me.
The way he used his variable was very elementary and I do not understand why no one before
