Takeaways

• 📊 Multiplication charts can be overwhelming, but there are hacks to simplify them.
• ✏️ Multiplication with 1 and 10 is straightforward; 1 times any number is that number, and 10 times any number simply adds a zero.
• 📖 Multiplying by 11 is easy by doubling the number (e.g., 2 x 11 = 22).
• 🖩 If numbers get difficult, it's okay to use a calculator.
• ✌️ Multiplying by 2 is simple and results in even numbers, and multiplying by 4 is just doubling the result of 2.
• 🔢 Counting by 3s (3, 6, 9, 12...) makes multiplying by 3 easier.
• 🧠 A trick for multiplying by 12 is to break it down: multiply by 10 and then by 2, and add the results.
• 🖐 A finger trick for multiplying by 9 involves folding down a finger to get the answer.
• 🃏 Square numbers (e.g., 6 x 6 = 36) are usually familiar, and knowing them helps reduce the complexity of the chart.
• 📚 Using flashcards for the most challenging problems (e.g., 6 x 7, 6 x 8, 7 x 8) helps reinforce learning.
