Real Life Math: Average
An average is a number that expresses the central tendency of a group of numbers. Another word for average, one that is used more often in science and math, is “mean.” Averages are often used when people need to understand groups of numbers. Whenever groups of measurements are collected in biology, physics, engineering, astronomy or any other science, averages are calculated. Averages also appear in grading, sports, business, politics, insurance, and other aspects of daily life. An average or mean can be calculated for any list of two or more numbers by adding up the list and dividing by how many numbers are on it.
Real Life Math: Addition
Math in SPORTS AND FITNESS ADDITION
Many aspects of popular sports require the use of addition. For example, some of the best-known records tracked in most sports are found by simply adding one success to another. Records for the most homeruns, the most 3-point shots made, the most touchdown passes completed, and the most major golf tournaments won in a career are nothing more than the result of lengthy addition problems stretched out over an entire career. On the business side of sports are other addition applications,including such routine tasks as calculating the number of fans at a ballgame or the number of hotdogs sold, both of which are found by simply adding one more person or sausage to the running total.
