Key Takeaways. Think of algebraic expressions as generalizations of common arithmetic operations that are formed by combining numbers, variables, and mathematical operations. The distributive property a (b + c) = ab + ac, is used when multiplying grouped algebraic expressions.
An algebraic expression is an expression that includes algebraic terms. Algebraic terms are individual letters, groups of letters, or groups of letters and numbers separated by addition or subtraction. Other operations (like multiplication, division, and exponents) happen within an algebraic term. Individual numbers are known as constant terms.
