What is an algebra expression you replace each variable with a number?
evaluation, evaluate.
How do you evaluate a math expression?
The evaluate a algebraic math expression you first must substitute a number for each variable. Then you must perform the operation in the correct order.
How do you evaluate the expression P86?
If it is a variable-name, then just fetch the value of the variable.
How do you find a specific numerical value for an algebraic expression?
you have to deduce the variable and evaluate the expression.

To evaluate a variable expression you must do what to values for the variable?
You must substitute values for the variable.
What do you need to be given to evaluate an algebraic expression?
A variable

What is the meaning of evaluate in maths?
In mathematics, to evaluate means to find the numerical value of an expression or equation. This often involves substituting given values for variables and simplifying the expression using mathematical operations such as addition, subtraction, multiplication, and division. Evaluation is a fundamental process in mathematics that allows us to determine the specific numerical result of a mathematical statement.
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
How do you evaluate variable expressions?
To evaluate a variable expression, replace all the variables with numbers and simplify the resulting numerical expression. 3m for m = 9 3(9)=27
What must you do to evaluate a variable expression?
you have to undo what ever's being done to the variable :p
