Definition of Expression. An Expression is a mathematical phrase that combines numbers and/or variables using mathematical operations. An expression is a representation of a value; for example, variables and/or numerals that appear alone or in combination with operators are expressions.
A mathematical expression can be as simple as 2 + 4 or as complex as -4xy + 8 x - 5(x/y). All mathematical expressions contain terms and each term has a coefficient, the numerical factor.
