Multiply 1-digit numbers by larger numbers

Key points :

✅ What Does It Mean?

Multiplying a 1-digit number by a bigger number means adding that bigger number again and again.
Example: 6 × 4 = 4 + 4 + 4 + 4 + 4 + 4 = 24 ✨

---

🔢 Place Value Matters!

Break the larger number into Tens and Ones to multiply easily.
Example:
7 × 23
→ 23 = 20 + 3
→ 7 × 20 = 140
→ 7 × 3 = 21
→ Total = 161 🎯

---

🧠 Use Distributive Property

This property helps to split the number to multiply easily:
a × (b + c) = (a × b) + (a × c)
Example: 6 × 15 = (6 × 10) + (6 × 5) 🙌

---

🔁 Repeated Addition (Quick Check!)

Multiplication is the same as repeated addition.
8 × 5 = 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 🧮

---

🧩 Multiplying With Zero

Any number multiplied by 0 is 0.
Example: 7 × 0 = 0 🚫

---

⭐ Multiplying With 1

Any number multiplied by 1 stays the same.
Example: 1 × 54 = 54 👍

📊 Use Mental Math Tricks

• Double it for ×2
• Triple it for ×3
• Add zero once for ×10
  Example: 8 × 10 = 80 💡

🔍 Estimate to Check Your Answer

Round the larger number to the nearest 10 and multiply to check if your answer is reasonable.
Example:
9 × 48 ≈ 9 × 50 = 450 🧠✅
