What else can I help you with?
What do you call a number variable or answer in an expression?
A number variable or answer in an expression is typically referred to as a "value." In mathematics, it can also be called a "numerical value" or "constant" if it doesn't change. When dealing with algebraic expressions, variables often represent unknown values and can take on different numerical values depending on the context.
Does an algebraic expressions have a single value?
Not necessarily.
What is a variable term?
A variable term is a component of an expression that includes a variable, which is a symbol representing an unknown value, often denoted by letters such as x or y. Variable terms can be combined with coefficients (numerical factors) to form algebraic expressions, such as 3x or -5y. In contrast, constant terms are numbers without variables. Together, variable and constant terms form the building blocks of algebraic equations and expressions.
What does it mean to find the value of an algebraic expression?
When a given set of values for the variables are substituted in the expression the result is the value of the expression.
How algebraic expressions formed?
Algebraic expressions are formed by combining numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division. A variable represents an unknown value and is typically denoted by letters like x or y. For example, the expression 3x + 5 represents three times a variable x plus five. The structure of these expressions allows for the representation of mathematical relationships and the solving of equations.
How can you have different values in algebraic expressions?
When the value of a variable in an algebraic expression changes, the value of the expression can change.

Can you explain the significance of the keyword "1x-9" in the context of algebraic expressions?
In algebraic expressions, the keyword "1x-9" represents a linear equation with one variable (x) and a constant term (-9). This expression is significant because it helps to simplify and solve equations by isolating the variable and finding its value.
Does an algebraic expressions have a single value?
Not necessarily.

How do you find the value of an algebraic expression?
Take the value of each variable in the expression and replace the variable by its value. Then do the math!
When two expressions are equal in value?
They are callled: Identical equations or Identities See: http://www.tutorvista.com/search/value-algebraic-expressions
How do you find the value of an algebraic expression by substituting a number for each variable and simplifying?
The answer to the question is given in the question!If you want to find the value of an algebraic expression, then you need to substitute numerical values for each of the variables in the expression, and then calculate and simplify the result.
How do you evaluate an algebraic expression when I know the value of each variable?
Replace each variables in the algebraic expression by its [known] value and calculate the value (ie evaluate) of the algebraic expression.
What is to find the value of a numerical or algebraic expression?
to solve for the variable
What is x inceased by 6 in algebraic expressions?
In algebraic expressions, when we say "x increased by 6," we represent this as ( x + 6 ). Here, ( x ) is the variable, and adding 6 indicates that we are increasing the value of ( x ) by 6 units. This expression can be used in equations or functions where we need to express a quantity that is greater than ( x ) by 6.
