(noun)

values that contain exceptions to resolve the contradictions inherent between ideal values and practical realities.

Examples of real values in the following topics:

  • Imaginary Numbers

    • There is no such value such that when squared it results in a negative value; we therefore classify roots of negative numbers as "imaginary."
    • What does it mean, then, if the value under the radical is negative, such as in −1\displaystyle \sqrt{-1}√​−1​​​?
    • There is no real value such that when multiplied by itself it results in a negative value.
    • This means that there is no real value of xxx that would make x2=−1x^2 =-1x​2​​=−1 a true statement.
    • When the radicand (the value under the radical sign) is negative, the root of that value is said to be an imaginary number.
  • Calculating Real GDP

    • Real GDP growth is the value of all goods produced in a given year; nominal GDP is value of all the goods taking price changes into account.
    • The real GDP is the total value of all of the final goods and services that an economy produces during a given year, accounting for inflation .
    • In economics, real value is not influenced by changes in price, it is only impacted by changes in quantity.
    • Real values measure the purchasing power net of any price changes over time.
    • Real GDP accounts for inflation and deflation.
  • Ideal vs. Real Culture

    • When we talk about American values, we often have in mind a set of ideal values.
    • Along with every value system comes exceptions to those values.
    • With these exceptions, real values emerge.
    • Whereas we might refer to ideal values when listing American values (or even our own values), the values that we uphold in daily life tend to be real values.
    • In ideal culture, marriage is forever, but in real culture, many marriages end in divorce.
  • Absolute Value

    • Absolute value can be thought of as the distance of a real number from zero.
    • In mathematics, the absolute value (sometimes called the modulus) of a real number aaa is denoted ∣a∣\left | a \right |∣a∣.
    • For example, the absolute value of 5 is 5, and the absolute value of −5 is also 5, because both numbers are the same distance from 0.
    • When applied to the difference between real numbers, the absolute value represents the distance between the numbers on a number line.
    • Other names for absolute value include "numerical value," "modulus," and "magnitude."
  • Other Considerations in Capital Budgeting

    • The real option creates economic value by generating future decision rights for management.
    • A key feature is that the real option creates economic value by generating future decision rights - specifically, by offering management the flexibility to act upon new information such that the upside economic potential is retained while the downside losses are contained .
    • Another value-creating aspect of real options can be found in abandonment.
    • Real investments are often made not only for immediate cash flows from the project, but also for the economic value derived from subsequent investment opportunities.
    • Projects with real options can be evaluated using a range of possible profits.
  • Visualizing Domain and Range

    • In other words, two different values of xxx can have the same yyy-value, but each yyy-value must be joined with a distinct xxx-value.  
    • Both graphs include all real numbers xxx as input values, since both graphs continue to the left (negative values) and to the right (positive values) for xxx (inputs).  
    • The curves continue to infinity in both directions; therefore, we say the domain for  both graphs is the set of all real numbers, notated as: R\mathbb{R}R.
    • The graph of f(x)=x2f(x)=x^2f(x)=x​2​​ (red) has the same domain (input values) as the graph of f(x)=−112x3f(x)=-\frac{1}{12}x^3f(x)=−​12​​1​​x​3​​ (blue) since all real numbers can be input values.  
    • The range of the blue graph is all real numbers, R\mathbb{R}R.
  • Differences Between Real and Nominal Rates

    • The real rate is the nominal rate minus inflation.
    • In the case of a loan, it is this real interest that the lender receives as income.
    • A lender would have no net benefit from such a loan because inflation fully diminishes the value of the loan's profit.
    • Where r is the real rate, i is the inflation rate, and R is the nominal rate.
    • The real rate can be described more formally by the Fisher equation, which states that the real interest rate is approximately the nominal interest rate minus the inflation rate: 1 + i = (1+r) (1+E(r)), where i = nominal interest rate; r = real interest rate; E(r) = expected inflation rate.
  • Zeros of Polynomial Functions with Real Coefficients

    • A root, or zero, of a polynomial function is a value that can be plugged into the function and yield 000.
    • The zero of a function, f(x)f(x)f(x), refers to the value or values of xxx that will result in the function equaling zero, f(x)=0f(x)=0f(x)=0.
    • This section specifically deals with polynomials that have real coefficients.
    • (An example of a non-real number would be −1\sqrt -1√​−​​​1.)
    • Even though all polynomials have roots, not all roots are real numbers.
  • The GDP Deflator

    • Nominal GDP, or unadjusted GDP, is the market value of all final goods produced in a geographical region, usually a country.
    • That market value depends on the quantities of goods and services produced and their respective prices.
    • In other words, real GDP is nominal GDP adjusted for inflation.
    • Real GDP reflects changes in real production.
    • It is calculated by dividing nominal GDP by real GDP and multiplying by 100.
