How do you evaluate an expression when given values for the variables?
You replace each variable by its value. Then you do the indicated calculations.
A combination of numbers variables and mathematical operations arranged in meaningful order?
variable 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 is an expression that consists of numbers operations and grouping symbols?
Numerical Expression
What is an expression that combines numbers and operations?
It is simply a more complicated expression.
Does a variable expression consist of numbers variables and operations?
Yes. A variable expression is also known as an algebraic expression. An equation consists of variable expressions on each side of an equality.
What are numbers operations and unknown values?
variable expression, I believe.
How do you evaluate an expression when given values for the variables?

Do a variable expression consist only of numbers?
No, because numbers never vary. A variable expression must have something in it that can take on different values, usually a letter, like 'x' for example.

variable expression(;
What expression consists of numbers and operations?
algebraic expression consists of numbers and operations
What is the difference between a numerical expression and a variable expression?
A variable expression includes variables.
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.
A combination of operations on variables and numbers is called an?
This is called algebra. In algebra you can have many operations. You can add, subtract, multiply, divide, square, cube, square root, factor, or distribute. There are others but these are the main ones. You use these operations to find the numerical value of the variable.
Is the set of numbers that can replace the variable in an algebraic expression.?
It is the domain of the expression.
What is a variable of variables numbers and symbols?
It is an expression.
What is an expression that consists of numbers operations and grouping symbols?
Numerical Expression
