Properties of Real NumbersVideos, worksheets, and activities to help Algebra students.
Introduction to Real Numbers When analyzing data, graphing equations and performing computations, we are most often working with real numbers. Real numbers are the set of all numbers that can be expressed as a decimal or that are on the number line. Real numbers have certain properties and different classifications, including natural, whole, integers, rational and irrational.
Analyzing Data There are different methods we use for analyzing data. Some of the most common ways that we analyze data is to identify the mean, median and mode of a set of numbers. When analyzing data we are sometimes asked to use a box and whisker plot, or to find the percentiles of a list of numbers. These methods for analyzing data deal are used for real numbers and can be decimals, integers, or another classification of the real numbers. Properties of Real Numbers When analyzing data or solving problems with real numbers, it can be helpful to understand the properties of real numbers. These properties of real numbers, including the Associative, Commutative, Multiplicative and Additive Identity, Multiplicative and Additive Inverse, and Distributive Properties, can be used not only in proofs, but in understanding how to manipulate and solve equations.
