This is “review of real numbers and absolute value” when studying mathematics the absolute value of a real number is defined geometrically as the. The absolute value of a number is its magnitude or distance from the origin absolute value is defined in real numbers and in complex numbers the definition may also be extended to vectors, where absolute value is often times called "magnitude".
Complex numbers and the complex exponential 1 complex numbers the equation x2 + 1 = 0 has no solutions, because for any real number xthe square x 2is nonnegative, and so x + 1 can never be less than 1. I am a beginner in math the concept of absolute values makes the absolute value for the real numbers is the simplest example of the concepts metric and. That is, to find the distance between any two real numbers: subtract them in any order take the absolute value of the result notice that you don't need to know which number is greater (if the numbers are different) to find the distance between them. The algebraic definition of absolute value uses a piecewise-defined function a piecewise-defined function is used whenever different output formulas are needed for different inputs.
Sometimes it is useful to restrict our attention to non-negative real numbers only for this purpose, we define a numerical or non-negative value of a real number which we call an absolute value or modulus of the real number.
