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.
It is called an expression.
An expression.
Yes, an algebraic expression needs no operation and can have multiple variables.
A scientist, for example.
The definition is A combination of variables, numbers, and at least one operation.
Expression
A combination of variables,numbers,and at least one operation!
complex numbers
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.
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.
Equation
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
It is called an expression.
An expression is a mathematical phrase that combines numbers, variables, and at least one operation, such as addition, subtraction, multiplication, or division. For example, (3x + 5) is an expression that includes the variable (x), the number (5), and the operation of addition. Expressions do not include equality signs, making them distinct from equations. They can be simplified or evaluated for specific values of the variables.
An expression that combines variables, numbers, and at least one operation is a mathematical statement that represents a value. For example, the expression (3x + 5) includes the variable (x), the number 3, and the number 5, along with the operation of addition. Such expressions are fundamental in algebra, allowing us to formulate equations and solve for unknowns.
