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.
How do you find a specific numerical value for an algebraic expression?
you have to deduce the variable and evaluate the expression.
To find the value of a numerical of algebraic expression?
Evaluate using PEMDAS
How do you evaluate a expression?
Replace all the variables in the expression by their numerical values and calculate the result.
What is used to evaluate an algebraic expression for a specific value?
It is done by substituting the values of the variables in the expression and then hope that you are capable of evaluating the result.

How so you evaluate an expression?
The idea is to replace any variables (if there are any) by their numerical values, then do all the calculations.
What is the difference between simplifying and evaluating algebraic expressions?
Simplifying an expression is getting rid of any brackets or parentheses, performing as many operations as you can - including combining like terms. To evaluate an expression you would substitute the numerical values of all the variables, carry out all the operations (addition, multiplication etc) in the expression to reach the answer - the numerical value of the expression.
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
