An equation.
complex numbers
the order of operations
The definition is A combination of variables, numbers, and at least one operation.
Expression
A combination of variables,numbers,and at least one operation!
variable expression(;
A combination of numbers, variables, and mathematical operations arranged in a meaningful order is known as an expression. An expression can include constants (numbers), variables (like x or y), and operators (such as addition, subtraction, multiplication, and division). It represents a value or a relationship between quantities, but it does not include an equality sign. For example, (3x + 5) is an algebraic expression.
i don't have a clue
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.
Term- a number, a variable, or a product of numbers and variables.
What is a math sentence that compares unequal expressions using one or more symbols
A combination of variable numbers and at least one operation can be expressed as an algebraic expression. For example, in the expression (3x + 5y - 2), (x) and (y) are variable numbers, while the operations are addition and subtraction. This combination allows for the representation of relationships between quantities that can change.
