A combination of numbers, a variable, and at least one operation can be represented mathematically as an expression. For example, in the expression ( 3x + 5 ), ( 3 ) and ( 5 ) are numbers, ( x ) is the variable, and the operation is addition. This expression illustrates how numbers and a variable can interact through mathematical operations.
An algebraic expression contains variable numbers and at least one operation. For example, the expression (3x + 5) includes the variable (x) and the operations of addition and multiplication. Such expressions can represent a wide range of mathematical relationships and can be simplified or solved for specific variable values.
The definition is A combination of variables, numbers, and at least one operation.
Expression

It is an algebraic expression.
2×+4×-5 An expression does not have an equal sign but can be solved has numbers, variables, and at least one operation
An expression.
The definition is A combination of variables, numbers, and at least one operation.
Expression
A combination of variables,numbers,and at least one operation!
That looks like the description of an EXPRESSION. However, an expression need not have "at least one operation"; a single number, or variable, is a perfectly valid expression.
An expression.
An algebraic expression can have a mixture of numbers and variables, but it does not contain an equals sign.
It is an algebraic expression.
Equation
It is an algebraic expression.
It is called an expression.
