What is expression?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between. In math, there are two types of expressions, numerical expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. The terms involved in an expression in math are:

  • Constant: A constant is a fixed numerical value.
  • Variable: A variable is a symbol that doesn't have a fixed value.
  • Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.
  • Coefficient: A coefficient is a number that is multiplied by a variable in an expression.

5(2x - 3) - 3(x + 4) / 9

=10x-15-3x-12/9

=10x-3x-15-12/9
