Explanation of How to Solve These Problems

These are basic single-digit multiplication facts, often called “times tables.” Here’s how you can think about and solve them:

#### 1. Understand Multiplication as Repeated Addition
- For example, `5 × 9` means adding 5 nine times:
`5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 = 45`
- Or, adding 9 five times:
`9 + 9 + 9 + 9 + 9 = 45`

#### 2. Use Known Facts or Patterns
- Multiplying by 0: Any number × 0 = 0.
- Multiplying by 1: Any number × 1 = itself.
- Multiplying by 2: Just double the number (e.g., 8 × 2 = 16).
- Multiplying by 5: The answer ends in 0 or 5 (e.g., 5 × 9 = 45).
- Multiplying by 9: The digits of the answer add up to 9 (e.g., 9 × 8 = 72 → 7 + 2 = 9).

#### 3. Memorize the Times Tables
- The best way to get fast and accurate at these is to memorize the multiplication table from 1×1 to 10×10.
- Flashcards, songs, or apps can help with this.

#### 4. Check Your Work
- You can reverse the multiplication to check:
If `8 × 4 = 32`, then `32 ÷ 4` should equal 8.
