Algebraic expressions may contain variables but they are not normally called variables. In fact, if they are related to identities, they need not be variable.
For example, (4x2 + 8xy + 4y2)/(x + y)2 is an algebraic expression, but it is not a variable: it equals 4.

What is a mathematical phrase that contains operations numbers or variables?
A mathematical phrase that contains operations, numbers, or variables is called an algebraic expression. Algebraic expressions consist of constants (numbers), variables (letters representing unknown quantities), and mathematical operations such as addition, subtraction, multiplication, division, and exponentiation. These expressions can be simplified, evaluated, or manipulated using algebraic rules and properties.
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.
An algebraic expression is a combination of letters called what?
variables
How are algebraic expressions and equations alike?
Algebraic expressions are the written relations of or between variables. For example, x2, 1/x, and x + y + z are all algebraic expressions. Algebraic equations are simply algebraic expressions that equate to something. For example, x2 = 4, 1/x = y, and x + y + z = 42 are all algebraic equations. In general, one differentiates algebraic expressions from exponential, trigonometric, hyperbolic, and logarithmic expressions by requiring algebraic expressions to be confined to polynomial expressions. I've added a link regarding polynomials below.
How do you evaluate algebraic expressions?
Replace the variables with the correct values and calculate using the order of operations
What is the difference between algebraic and numerical expressions?
Algebraic expressions use letters as variables to represent numbers. Ex. 5c-(2+x) x=2 c=12 Numerical expressions use numbers only. Ex. 12+(2-7)
What is a expression with variables called?
It's called an algebraic expression.
What describes a relationship between several variables in an algebraic equation?
an algebraic equation that describes a relationship between several variables is called a?
What do you call the result after multiplying a set of numbers or algebraic expressions?
The product is the result after multiplying a set of numbers or algebraic expressions
What is a mathematical phrase containing numbers and operation symbols?
Algebraic expressions is a mathematical phrase that contains operations numbers or variables.
Do algebraic expressions have equals signs?
no algebraic expressions do not have equal signs but equations do.
How do you classify algebraic expressions?
Algebraic expressions are terms that do not include an equality sign
