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.

What is an expression that contains a variable a number and at least one operation?
That looks like the description of an EXPRESSION. However, an expression need not have "at least one operation"; a single number, or variable, is a perfectly valid expression.
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.
What would the variable expression be for double a number f?
2f
Which is the variable expression for Seventeen decreased by a number y?
17 - y
Translate the phrase into a variable expression Five more than a number?
N + 5 With "N" being the variable.
What do you call replacing a variable in an expression by a number and simplifying the result?
That is called 'solving'.
To find the value of an algebraic expression by substituting a number for each variable and simplifying?
322
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 each variable with a number in an expression and simpiifying the result?
Evaluating the expression.
What is replacing a variable in an expression with a number value called?
Substituting.
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 the meaning of variable in algebraic expression?
Variable is any letter used in an algebraic expression, and can vary (change form) to be any number, and one variable means the same number in any single algebraic expression. Usually algebra is simplifying the expression or equation until you know what the variable is equal to.
When you replace the variable with a number and perform the operations you blank an expression?
When you replace the variable with a number and perform the operations, you evaluate an expression. This process involves substituting the numerical value for the variable and simplifying the expression according to the given operations. Evaluation is a fundamental concept in mathematics and is used to determine the value of the expression under specific conditions.
To find the value of an algebraic expression by subsituting a number for each variable and simplifying?
And the question is ...
What is an algebraic expression by replacing each variable with a given number and performing all operations?
It is called evaluating the equation.
Why replacing variable for a number in an expression or equation is called substituting?
Because you are substituting a number for a variable. Like substituting salt for sugar in a cake recipe. Although you really shouldn't do the latter.
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.
