The coefficient
In mathematics, a variable combined by multiplication or division with a number is referred to as a term. For example, in the expression (3x), the number 3 is multiplied by the variable (x). Similarly, in the expression (\frac{y}{4}), the variable (y) is divided by the number 4. These operations indicate a relationship between the variable and the constant through multiplication or division.
The number is called the coefficient of the variable
a variable expression
Substituting.
That is often called the coefficient.

The number that multiplies a variable in an algebraic expression is called a coefficient. It is the numerical factor that is multiplied by the variable to form a term in the expression.

That is often called the coefficient.
The expression "6a" is in linear form, where "6" is the coefficient and "a" is the variable. It represents a linear function with a slope of 6 if plotted on a graph. This expression can also be interpreted as a term in algebra that indicates multiplication of the number 6 by the variable "a."
A variable is a letter that represents a number. An expression that contains at least one variable is called variable expression, also called algebraic expression. A variable expression has one or more terms. A term is a number, a variable, or a product of numbers and variables. For example,3(x^2)y + 2xy + x - 7 is a variable expression, where you have 4 terms.When working with variable expression, you often use the substitution principle:If a = b, then a may be replaced by b in any expression.The set of numbers that a variable may be represent is called replacement set, or domain, of the variable. To evaluate a variable expression, you replace each variable with one of its values and simplify the numerical expression that results.Example: Evaluate the expression 2x - 4y for x = 5 and y = -9.Solution:2x - 4y= 2(5) - 4(-9)= 10 + 36=46
That is called 'solving'.
A number in front of a variable is called a coefficient. It represents how many times the variable is multiplied. For example, in the expression (3x), the number 3 is the coefficient of the variable (x). Coefficients can be positive, negative, or zero, and they play a crucial role in determining the value of the expression when the variable is assigned a specific number.
The algebraic expression for p multiplied by 3 is 3p. This is written as the coefficient (3) multiplied by the variable (p). In algebra, when a number is placed next to a variable without an explicit multiplication sign, it is understood to be multiplication. Therefore, 3p represents three times the value of p.
That looks like the description of an EXPRESSION. However, an expression need not have "at least one operation"; a single number, or variable, is a perfectly valid expression.
