Explanation:

1. Understanding Multiplication: Multiplication is essentially repeated addition. For example, \( 5 \times 6 \) means adding 5 six times: \( 5 + 5 + 5 + 5 + 5 + 5 = 30 \).
2. Using Known Facts: Many of these problems involve basic multiplication facts that are commonly memorized (e.g., \( 6 \times 6 = 36 \), \( 7 \times 7 = 49 \)).
3. Commutative Property: The order of factors does not matter in multiplication. For example, \( 3 \times 9 = 27 \) and \( 9 \times 3 = 27 \).
4. Patterns and Tricks: Some patterns can help solve problems quickly. For example, multiplying by 10 is easy because you just add a zero to the number (e.g., \( 10 \times 7 = 70 \)).
