Algebraic Expressions Vocabulary

Terms: Elements of a mathematical expression separated by addition or subtraction signs, e.g., in 3x + 5, both 3x and 5 are terms.
Like Terms: These are terms sharing the same variable raised to the same power, allowing for direct addition or subtraction, such as 2x and 4x.
Constant Term: This refers to a term consisting solely of a number without a variable, like 5 in the expression 3x + 5.
Coefficient: The numerical factor that precedes a variable in a term, for example, in 7x, 7 is the coefficient of x.
Expression: A mathematical phrase combining numbers and operations (such as addition, subtraction, multiplication, or division) but lacking an equal sign, e.g., 2x + 3.
Evaluate: The process of determining the value of a numerical or algebraic expression by substituting known values for the variables and performing the necessary calculations.
Variable: A symbol, typically letters like x or y, that represents an unknown or changeable quantity in mathematical or logical expressions.
Distributive Property: A fundamental property in algebra denoted as a(b + c) = ab + ac, allowing a number outside parentheses to be multiplied to each term inside them, facilitating expansion of expressions.
Combine Like Terms: The procedure of simplifying expressions by adding or subtracting terms that are alike, such as 3x and -5x combining to form -2x.
Equivalent Variable Expression: An expression that holds true for all values of its variables. For example, simplifying the expression 7c + 9 - 3c results in 4c + 9, demonstrating equivalence.
