### Alg2 sections 1, 2, and3

1. 1. ALGEBRA 2 Sections 1, 2, and 3
2. 2. Real Numbers Rational Numbers Irrational Numbers Integers Whole Numbers Natural Numbers See page 1
3. 3. Real Number Line ≈ 1.571 ≈ 3.464 -2.45
4. 4. Plot the numbers listed below on the real number line.
5. 5. How can we use them in math?  Add  Subtract Adding the opposite or additive inverse  Multiply  Divide Multiplying by the reciprocal or Multiplicative inverse
6. 6. Order of Operations  PEMDAS  Parenthesis  Exponents  Multiplication and division.  As they appear from left to right.  Addition and subtraction.  As they appear from left to right.
7. 7. Properties  Closure  Commutative  Associative  Identity  Inverse  Distributive Pages 3-4
8. 8. Unit Analysis  You work 4 hours and earn \$36. What is your earning rate?  You travel for 2.5 hours at 50 miles per hour. How far do you go?  You drive 45 miles per hour. What is your speed in feet per second? Page 5
9. 9. Numerical Expression  Base Exponen t
10. 10. Algebraic Expression  Has at least one variable Coefficients Variables Constant • Above is and expression written as a sum. • The parts added together are called terms. • Variable term has a variable. • A constant term has no variable.
11. 11. Solve linear Equations 
12. 12. Properties  Addition Property of Equality  Subtraction Property of Equality  Multiplication Property of Equality ◦ Nonzero number  Division Property of Equality ◦ Nonzero number
13. 13. Solving Equations  Simplify both sides following PEMDAS, and various properties.  Bring variables to one side  Undo the operations in reverse order, addition/subtraction, multiplication/division, powers, grouping symbols.
