When discussing mathematical problems, in expressions or equations related to specific variables (or unknown functions) and their derivatives, known functions or constants multiplied by unknowns are called coefficients. The term coefficient is also widely used in physics, engineering and computer technology. Such as the ratio of the partial value of a quantity to the total value, or some related figures in the relationship between the change of one quantity and the change of other quantities, are called coefficients. At this time, the coefficient is often preceded by the proper names of related phenomena or things, such as "expansion coefficient" and "carbolic acid coefficient". The numerical factor in the monomial is also called the coefficient of the monomial. The factor of the highest term in a polynomial is called the coefficient of the polynomial.
For example, the coefficient of 14m is 14. The coefficient of 123xsz is 123.
The coefficient of 2000ax is 2000.
The numerical factor in a single item is called its coefficient. The sum of the exponents of all the letters in a monomial is called its degree. For example, the coefficient of abc is 1 and the degree is 3.
The first coefficient of the functional relationship y=x+6 and y=x is the same, both of which are 1.
Usually the coefficient is not 0.

[Times]: the number of times the same action or event is repeated.
[Order]: refers to the number of torsional impact cycles or vibration cycles. For example, for the torsional vibration of the engine crankshaft, it refers to the number of impact cycles or vibration cycles per rotation of the shaft.
The exponent of all the letters in the monomial and the number of times it is called, such as abc, are all 3.
In a polynomial, the number with the highest exponent is called the degree of the polynomial.
Numbers greater than zero, such as 9 and 8. ...
Their time is zero.
If the number of 9 and 8 is zero, then they should be equal to zero. I think their number is 1. Please give the correct answer.
A single number can be regarded as a letter with an index of 0, so the sum of the indexes of letters is 0 and the number of times is 0.
Numbers have no time.
index
1. Mathematical concept: In the power n of a, where a is called the base, n is called the exponent, and the result is called the power.
2. Economic concept: from the definition of index, in a broad sense, the relative number formed by the comparison of any two values can be called index; The narrow index is a special relative number, which is used to measure the comprehensive changes of multiple projects in different occasions.
Statistics designed and calculated according to the prices of some sample stocks or bonds are used to measure the price fluctuation of the stock market or bond market. In the United States, for example, the common stock price indexes are Dow Jones Industrial Average and Staples 500 Enterprise Index. The most famous bond price indices are SalomonBrothersBondIndex and Sheeson-Lehman Bond Index. In China, there are circulation-weighted stock index, CITIC index and Xinhua index produced by Shanghai and Shenzhen stock exchanges.
