What does value of variables mean?
In algebra, variables are represented by letters such as x. A variable could be any number. That number is the "value" of the variable. In an expression, you can choose a number to put in for x, and simplify to get a number which is the value of the expression. In an equation, you can solve for the value of x, which will be the value of x which makes the equation true.
What is the meaning of the algebra term monomial?
any number or variable or product of numbers and variables
What do you call replacing a variable in an expression by a number?
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
What is the basic difference between algebraic expression and polynomial?
A polynomial is a type of algebraic expression. They differ in the number of terms that contain variables. An algebraic expression has at least 1 variable, while a polynomial has multiple terms with variables in it.
How do you write this variable expression The sum of one and a number added to the product of seventeen and a number?

What is the math term for a number a variable or a product of numbers and variables?

What is a number variable or a product of numbers and variables?
It is called a term.
Is a constant a number variable or the product of a number and one or more variables?
A constant is not a variable at all, and none of its factors was a variable. It is constant.
What is a number variable or the product of a number and one more variables raised to whole number powers?
It is the integral power of the number or the product of the number and variable(s). there is no special name.
Write the phrase as a variable expression the product of 9 and a number?
The expression is 9*x.

Does a variable expression consists only of numbers?
An algebraic expression can have a mixture of numbers and variables, but it does not contain an equals sign.
