Properties of Numbers & Equality Notes and Worksheets - Lindsay Bowden - Free Printable

Problem Overview:

The task is to fill in the blanks in the table that outlines the Properties of Equality. Each property has a definition and an example provided, and we need to complete the missing parts based on our understanding of these properties.

---

Solution:

#### 1. Addition Property
- Definition: You can add a number to both sides of an equation.
- Example: \( x - 3 = 10 \)

#### 2. Subtraction Property
- Definition: You can subtract a number from both sides of an equation.
- Example: \( x + 4 = 6 \)

#### 3. Multiplication Property
- Definition: You can multiply both sides of an equation by the same number.
- Example: \( \frac{x}{2} = 5 \)

#### 4. Division Property
- Definition: You can divide both sides of an equation by the same number.
- Example: \( 3x = 12 \)

#### 5. Reflexive Property
- Definition: A number or variable equals itself.
- Example: \( 10 = 10 \), \( a = a \)

#### 6. Symmetric Property
- Definition: If \( a = b \), then \( b = a \).
- Example: \( x = 3 \) is the same as \( 3 = x \)

#### 7. Transitive Property
- Definition: If \( a = b \) and \( b = c \), then \( a = c \).
- Example: If \( x + 2 = 10 \) and \( 10 = y \), then \( x + 2 = y \)

#### 8. Substitution Property
- Definition: If \( a = b \), then you can substitute \( a \) with \( b \).
- Example: If \( a = b \) and \( a + c = d \), then \( b + c = d \)
