Think of something or someone that does not change as constant. In math and science, a constant is a number that is fixed and known, unlike a variable which changes with the context. That idea crosses over to real life. If a friend is a constant in your life, that means they have always been with you and there for you. Constant: A symbol which has a fixed numerical value is called a constant. For example: 2, 5, 0, -3, -7, 2/7, 7/9 etc., are constants. In the expression 5x + 7, the constant term is 7. 1 fixed and invariable; unchanging. 2 continual or continuous; incessant. constant interruptions. 3 resolute in mind, purpose, or affection; loyal. nt ] A quantity that is unknown but assumed to have a fixed value in a specified mathematical context. A theoretical or experimental quantity, condition, or factor that does not vary in specified circumstances. Avogadro's number and Planck's constant are examples of constants. In mathematics, a coefficient is a multiplicative factor in some term of a polynomial, a series, or any expression; it is usually a number, but may be any expression. For example, if y is considered as a parameter in the above expression, the coefficient of x is −3y, and the constant coefficient is 1. 5 + y.

### What do u mean by variable?

https://whatis.techtarget.com/definition/variable

In programming, a variable is a value that can change, depending on conditions or on information passed to the program. Typically, a program consists of instruction s that tell the computer what to do and data that the program uses when it is running.

### Is 0 a positive constant?

https://math.stackexchange.com/questions/348147/positive-constant-scalar-definition

The most common usage in English is that zero is neither positive nor negative. That is "positive" is normally understood to be "strictly positive". In the same way, "greater than" is normally understood to mean "strictly greater than", as in k>j (not k≥j). This is just a matter of definition.

### Is 0 a constant number?

https://en.wikipedia.org/wiki/Constant_(mathematics)

Since c occurs in a term that does not involve x, it is called the constant term of the polynomial and can be thought of as the coefficient of x0; any polynomial term or expression of degree zero is a constant.

### What is the constant in algebra?

https://www.mathsisfun.com/definitions/constant.html

A fixed value. In Algebra, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number. Example: in "x + 5 = 9", 5 and 9 are constants. See: Variable.

### What is difference between constant and variable?

https://byjus.com/maths/difference-between-constants-and-variables/

Difference between Constant and Variables. A constant does not change its value over time. A variable on the other hand changes its value dependent on the equation. Constants usually represent known values in an equation, expression or in line of programming.

### Can constants be negative?

The minus sign is actually 'attached' to the constant in a way. Therefore, any time you see a minus to the left of a constant, it belongs to that constant. Again, a minus or negative sign is to the left of the 3, so we get a -3 constant. There is also one just to the left of the 4, so we get a -4 constant.

### What is the constant and variable?

Constants and Variables. Constant : A symbol having a fixed numerical value is called a constant. OR. The number before an alphabet (variable) is called a constant. Variable : A symbol which takes various numerical values is called a variable.

### What is the synonym of constant?

### How do you find a constant?

https://www.sparknotes.com/math/algebra1/variation/section1/

Since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is y = 3x.

### What is the mean of constraints?
