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.
Math terms are commonly seen in algebra equations. Using operators, such as addition and subtraction signs, terms are grouped together to form an expression. Each number in the equation represents a single term. For example: In a straightforward arithmetic problem, the first and second numerical terms are added, subtracted or multiplied together to find the term that provides the answer to the problem.
