People use algebra in their daily lives when they make decisions about health, fitness, financial and money matters and when cooking. Algebra involves the use of known variables and fixed numbers in equations to find the values of unknown numbers.Continue Reading
Financial planning is an area in daily life where algebra is used. Algebra concepts are used to calculate items like interest rates and determine loan payments. They are also used to predict the growth of money.
Getting and staying physically fit often requires the use of calculations to determine if one has an appropriate level of body fat and body weight versus lean muscle and bone. It also involves determining the right amount of daily food intake and the types of foods appropriate for an individual's diet. Given known variables, such as height, activity and current percentages of body mass, algebra can be used to determine unknown variables necessary to reach and maintain fitness.
People who cook, either professionally or for personal use, use simple algebraic expressions to adjust the ingredients in a dish depending on the number of servings desired. Medical professionals use algebra in a variety of applications, such as determining drug dosage and measuring the performance of body functions, such as cardiac output.Learn more about Algebra
No single person discovered algebra, since various people in different parts of the world discovered it at different times. Some aspects of algebra were even discovered multiple times by different people who were unaware of each other. Virtually every major civilization worked out some portion of the algebraic puzzle, although certain people like Diophantus, Muhammad Ibn Musa al-Khwarizmi and Gottfried Leibniz made more significant contributions.Full Answer >
Algebra has been developed over thousands of years in several different countries. The earliest methods for solving mathematical problems with one or more unknown quantities come from ancient Egypt. The word "algebra" itself is derived from the title of Baghdad mathematician Al-Kwarizmi's 9th century book, "Hidab al-jabr wal-muqubala."Full Answer >
