This course, taught by Harvey Mudd College Professor Mohamed Omar, demonstrates how fundamental arithmetic abilities may improve your life in areas such as personal money, health, and social responsibility. The course covers topics such as how to save for retirement, what type of insurance to buy, getting a mortgage, deciding whether to rent or buy a home, lowering your carbon impact, and other life situations that benefit substantially from quantitative analysis.
