Study Notes
Rational Numbers
- Add, subtract, multiply, and divide rational numbers
- Example 1: -5 x 12 = -60
- Example 2: -77 + (-11) = -88
- Example 3: -33 + 22 = -55
- Example 4: -78 + 81 = 3
- Example 5: 3.7 - (-1.3) = 3.7 + 1.3 = 5
- Example 6: (-0.5)(-40) = 20
- Example 7: 2/10 + 4/10 = 0
- Example 8: (-1/4) * (3/8) + 9/12 = (-3/32) + 9/12 = (-3/32) + 3/4 = (-3/32) + 24/32 = 21/32

Evaluating Expressions
- Evaluate expressions with given values for variables
- Evaluate expressions using the order of operations
- Identify the constant, variable, coefficient, and term
- Example Problem: Evaluate the expression y - 2x + 6
Using Distributive Property
- Simplify expressions using the distributive property
- Example: Simplify the expression 9(4x-23)
- Answer = 9(4x) - 9(23) = 36x - 207
- Example: Simplify the expression -5(7y - 10)
- Answer = -5(7y) - -5(10) = -35y +50
