Differentiate Between Constants and Variables in a Given Algebraic Expression Performance Standard: The learner is able to model situation using oral, written, graphical and algebraic methods in solving problems involving algebraic expressions, linear equations, and inequalities in one variable. Content Standard: The learner demonstrate understanding of key concept of algebraic expressions, the properties of real numbers as applied in linear equations, and inequalities in one variable. Learning Competencies: Differentiate Between Constants and Variables in a Given Algebraic Expression. M7ME-IIb-24 An algebraic expression is any combination of one or more constant and variables along with at least one mathematical operation. A variable is any symbol representing possible values of a quantity. A constant is any symbol representing one fixed value. A term is a constant, a variable, or a product or a quotient of constant and variables. Terms are separated by the symbols + and -. A numerical coefficient is the constant factor in a monomial. A literal coefficient is/are the variable factor/s in a monomial. Examples: Identify the constant/s, variable/s, numerical coefficient, literal coefficient, and number of terms. Constant Variable Numerical Literal Number of Coefficient Coefficient Terms 1. 7a3 0 a 7 a3 1 2 2 2. 3x + 1 1 x 3, 1 x 2 3. 10ab + 2 2 a,b 10, 2 a,b 2 3 3 4. 5m -3n -7 -7 m,n 5, -3, -7 m ,n 3 5 7abc + 12xy - 3 -3 a,b,c,x,y 7, 12. -3 abc, xy 2 Activity: Identify the constant/s, variable/s, numerical coefficient, literal coefficient, and number of terms.
