Study Notes
Math Vocabulary Study Notes
-
Value: To evaluate an algebraic expression, substitute a specific value for the variable present in the expression.
-
Factors: In the algebraic expression 3(x - 2), the components 3 and (x - 2) are considered factors.
-
Properties of Operations: Equivalent expressions can be generated using properties such as the commutative and associative properties of operations.
-
Combine Like Terms: The expression 4x + 2x - 6y requires combining like terms (like 4x and 2x) to simplify.
-
Expand: The distributive property is utilized to expand algebraic expressions, such as transforming 5(x - 7) into 5x - 35.
-
Variable: In the expression 6x + 10, 'x' serves as the variable that represents an unknown value.
-
Coefficient: In the expression 6x + 10, the number 6 is identified as the coefficient of the variable x.
-
Constant: The number 10 in the expression 6x + 10 acts as the constant, which remains unchanged regardless of the variable's value.
-
Operations: Addition, subtraction, multiplication, and division are fundamental operations that can be applied to expressions.
-
