Finding the value of an algebraic expression by replacing variables with numbers called what?
Evaluating the expression
What is the process for evaluating expressions called?
An algebraic expression is a process for evaluating expressions. Replacing variables with numerals and following a standard order of operations is used for the process.
What do yo call replacing a variable in a algebraic expression with a quantity?
Substitution
What does it you to evaluate an algebraic expression?
To evaluate an algebraic expression means to simplify the expression as much as possible by replacing the variables in an expression with the numerical values given to you.Ex:Example of Evaluating an Algebraic ExpressionTo evaluate the algebraic expression '4.5 + x' for x = 3.2, we need to replace x with 3.2 and then add. 4.5 + x = 4.5 + 3.2=7.7Solved Example on Evaluating an Algebraic ExpressionEvaluate the algebraic expression p + 3q + 2p - 3q, for p = 2 and q = - 5.Choices:A. 12B. 18C. 3D. 6Correct Answer: DSolution:Step 1: p + 3q + 2p - 3q [Original expression.]Step 2: = (p + 2p) + (3q - 3q) [Group the like terms together.]Step 3: = 3p [Solve within the grouping symbols.]Step 4: = 3 x 2 [Substitute 2 for p.]Step 5: = 6 [Multiply.]
What is value of an expression?
When you have an algebraic expression with variables in it, you need to know the the value of each variable. The value of the expression is found by replacing the variables with their values and simplifying. For example, evaluate 2xy-3x if x=5 and y=-1. 2xy-3x = 2*5*(-1) -3*5 = -10-15 = -25.
What do you call replacing a variable in an algebraic expression with a quaintity?
I think it is called "replacing" or "substitution".

What do you call replacing a variable in an in a algebraic expression with a quantiy?
When you replace a variable with a quantity, it is called a substitution.
Replacing each variable with a number in an expression and simplifying the result?
Substituting a numerical value for each variable in an expression and then simplifying the resulting expression is known as evaluating the expression. This process involves following the order of operations, which includes performing operations inside parentheses first, then exponents, multiplication and division from left to right, and finally addition and subtraction from left to right. By replacing variables with specific numbers, we can determine the exact value of the expression based on those inputs.

Evaluating the expression.
What is replacing each variable in an expression by a number and calculating the answer?
That is sometimes known as EVALUATING the expression.
What is to replace a variable with a number or anotherexpression in an expression?
The term for replacing a variable with another value or expression is "substitution."
What is replacing a variable in an expression with a number value called?
Substituting.
