- 1. Differentiates algebraic expressions, equations and inequalities. Prepared by: Vernon Sean Corteza GRADE 7
- 2. Lesson Objectives By the end of this lesson, students will be able to: • differentiate between algebraic expressions, equations, and inequalities; • identify whether a statement is an expression, an equation, or an inequality
- 3. Algebraic Expressions, Equations, and Inequalities Expressions, equations, and inequalities are used to describe relationships between quantities Expressi ons Equatio n Inequali tygreater than less than not equal less than or equal to greater than or equal to equal to constant, variables, and operation symbols
- 4. Algebraic Expression -is a mathematical phrase that can include numbers, variables, and operation symbols. It does not have an equality sign (=). Examples: • 3x + 5 • 2a - 4b + c • 7y + 10
- 5. Algebraic Equation - is a statement that asserts the equality of two expressions. It contains an equality sign (=). Examples: ⚬ x + 3 = 7 ⚬ 2a - 4b + c = 0 ⚬ 7y + 10 = 3y + 18 2
- 6. Algebraic Inequality- is a mathematical statement that compares two expressions and shows that one is greater than, less than, greater than or equal to, or less than or equal to the other. 2x + 3 < - y > 7x x + 7y - 7 < 2z >3
