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.
The definition is A combination of variables, numbers, and at least one operation.
Expression
It is an algebraic expression.
Equation
A mathematical expression is a combination of numbers, variables, and operation symbols that represents a value. It can include elements such as addition (+), subtraction (−), multiplication (×), division (÷), and parentheses to indicate the order of operations. For example, the expression (3x + 5) contains the variable (x), the number (3), and the operation of addition. Expressions do not include equality signs; that would make them equations.
complex numbers
The definition is A combination of variables, numbers, and at least one operation.
Expression
A combination of variables,numbers,and at least one operation!
The term for that is algebra.
Expression
An expression.
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.
An equation.
