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 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.
What is an algebraic substitution?
That means that you replace something, for something else. For example, a variable for a number, or a variable for some other expression.
What is the algebraic expression for the product of 14 times a number?
Assuming you call your number "n", the expression would be "14n". You can replace "n" with whatever variable you want to use.
What is a number that is multiplied by a variable in an expression?
The number is called the coefficient of the variable

What is an expression that is a number and a variable or a product of a number and one or more variables?
In Algebra a term is either a single number or variable, or numbers and variables multiplied together.
When you replace the variable with a number and perform the operations you blank an expression?
evaluate.

What does value of variables mean?
In algebra, variables are represented by letters such as x. A variable could be any number. That number is the "value" of the variable. In an expression, you can choose a number to put in for x, and simplify to get a number which is the value of the expression. In an equation, you can solve for the value of x, which will be the value of x which makes the equation true.
What is the algebraic expression for the product of 14 times a number?
Assuming you call your number "n", the expression would be "14n". You can replace "n" with whatever variable you want to use.
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.
What is a number that is multiplied by a variable in an expression?
The number is called the coefficient of the variable
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
What does the value of an expression mean?
If you replace variables in an expression by numbers (in case there are any variables) and then do the indicated operations, you get a number. That final number is the "value" of the expression.
What size is 2x?
It depends on the value of x. The x is a variable. To evaluate an expression, you need to have a value (number) to replace the x.
