In mathematics, a real number is a number that can be used to measure a continuous one-dimensional quantity such as a distance, duration or temperature. Here, continuous means that pairs of values can have arbitrarily small differences. Every real number can be almost uniquely represented by an infinite decimal expansion.
Real numbers include rational numbers like positive and negative integers, fractions, and irrational numbers. Any number that we can think of, except complex numbers, is a real number. Learn more about the meaning, symbol, types, and properties of real numbers.
Real numbers were created to distinguish the set of real numbers from imaginary numbers. Imaginary numbers are the result of trying to take the square root of a negative number. The set of real numbers is indicated using this symbol: ℝ. Below are a few examples of real numbers. 1; 0; 5.33333; ¼-7,200,568; π; The above is just a small sample ...
The Real Number Line is like a geometric line. A point is chosen on the line to be the "origin". Points to the right are positive, and points to the left are negative. A distance is chosen to be "1", then whole numbers are marked off: {1,2,3,...}, and also in the negative direction: {...,−3,−2,−1} Any point on the line is a Real Number:
A real number is a value that can represent any continuous quantity, positive or negative. Real numbers include integers, rational numbers, and irrational numbers.
