Constant was born at Gravesend, the son of Frederick Charles Constant and his wife Mary Theresa Tissie Hayne. His father was a dental surgeon in Folkestone. Hayne was educated at King s College Choir School Cambridge, King s School, Canterbury , The Technical Institute Folkestone, Sir Roger Manwood s School, Sandwich and Queens College, Cambridge .

The term constant dollars refers to a metric for valuing the price of something over time, without that metric changing due to inflation or deflation . The term specifically refers to dollars whose present value is linked to a given year. The principle, of course, can be applied to any currency worldwide, not only American dollars. See inflation adjustment and Real versus nominal value economics for more general discussions. Example Constant dollars are used to compare the real value of an income or price to put the nominal value in perspective. For example, who was making more money, your father who made 5,000 at his first job in 1957, or you when you started at 18,000 in 1986? The answer depends on how much can be purchased by each salary. Is a gallon of gasoline more expensive in 1972 than it is today? It depends on how long a person needs to work to earn the money to buy the gas. Converting the nominal values into constant dollars compares what 5,000 could buy in 1957 to what 18,000 could buy in 1986. It is similar to finding the common denominator when adding or comparing fractions. Is 5 8 bigger than 3 5? Convert them both to 40ths and the first becomes 25 40 and the 2nd 24 40. The inflation calculator at the Bureau of Labor Statistics shows that 5,000 in 1957 has a value of 19,501.78 in 1986 dollars ref http data.bls.gov cgi bin cpicalc.pl CPI Inflation Calculator Bot generated title ref or that 18,000 in 1986 has a value of 4,614.96 in 1957 dollars. So dad was making more money, even though 18,000 looks larger than 5,000. Any year can be used as a baseline for comparing two years as long as it is consistent. For example, both salaries could be converted into 1970 dollars. Then the 18,000 becomes 6,372.26 in 1970 dollars, and the 5,000 becomes 6,903.91 in 1970 dollars. The relative position stays the same no matter what year is used as a baseline. Also the fraction of 1986 salary 1957 salary remains the same as well when both are in constant dollars.

Unreferenced date December 2009 In mathematics , a constant term is a term mathematics term in an Expression mathematics algebraic expression that does not contain any Variable mathematics variables , and therefore has constant function constant value. For example, in the quadratic polynomial math x 2 2x 3, math the 3 is a constant term. After like terms are combined, an algebraic expression will have at most one constant term. Thus, it is common to speak of the quadratic polynomial math ax 2 bx c, math where x is the variable, and has a constant term of c . If c 0, then the constant term will not actually appear when the quadratic is written. Any polynomial written in standard form has a unique constant term, which can be considered the coefficient of x sup 0 sup . In particular, the constant term is always the lowest Degree of a polynomial degree term of the polynomial. This also applies to multivariate polynomials. For example, the polynomial math x 2 2xy y 2 2x 2y 4 math has a constant term of &minus 4, which can be considered the coefficient of x sup 0 sup y sup 0 sup . For any polynomial, the constant term can be obtained by substituting in 0 for all of the variables. The concept can be extended to power series and other types of series in the power series math a 0 a 1 x a 2 x 2 a 3 x 3 cdots, math a sub 0 sub is the constant term. In general a constant term is one that does not involve any variables at all. However in expressions that involve terms with other types of factors than constants and powers of variables, the notion of constant term cannot be used in this sense, since that would lead to calling 4 the constant term of math x 3 2 4 math , whereas substituting 0 for x in this polynomial makes it evaluate to 13.
