What does expressions contain?
Expressions have to contain numbers and letters.
What is an expression that substitutes numbers for the variables in the expressions?
It is "evaluating".
Is x-x a variable expression?
Yes. It is equal to zero. Yes, mathematical expressions can contain numbers, variables, and mathematical operations but do not contain an equal sign or inequality sign.
Does a equation only contain numbers?
No, it can contain variables.
What is expressions that contain only numbers and operations?
numerical expression
What is a mathematical phrase containing numbers and operation symbols?
Algebraic expressions is a mathematical phrase that contains operations numbers or variables.

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.
Do All expressions contain variables?
No, not all expressions contain variables. An expression is a mathematical phrase that combines numbers, variables, and mathematical operations. A variable is a symbol that represents a quantity that can vary, such as x or y. Some expressions may only contain numbers and mathematical operations, such as addition, subtraction, multiplication, and division. For example, "3 + 5" is an expression that only contains numbers and the addition operation. However, an expression that contains at least one variable is known as an algebraic expression, and this type of expression is commonly used in algebra to represent mathematical relationships between variables. For example, "2x + 4" is an algebraic expression that contains the variable x and represents a linear equation in which y is equal to two times x plus four.

A combination of variables numbers and at least one operation?
That sounds like the description of an "expression", except for one detail: an expression MAY have operations, but also, it may not, since numbers and variables are themselves expressions.
What is a combination of variables and numbers and an operation?
complex numbers
Does a equation only contain numbers?
