🔢 Problem 1: `625 × 53`
Step 1: Multiply 625 by 3 (units digit of 53):
625
× 3
= 1875
Step 2: Multiply 625 by 50 (tens digit of 53 → 5 × 10 = 50):
625
× 50
= 31,250 *(shift one place left because it’s ×50)*
Step 3: Add the two results:
1,875
+ 31,250
=
33,125
✔ Answer: 33,125

🔢 Problem 3: `6,093 × 5`
6,093
× 5
= 30,465
✔ Answer: 30,465

🔢 Problem 4: `4921 × 73`
Step 1: Multiply 4921 by 3:
4921
× 3
= 14,763
Step 2: Multiply 4921 by 70:
4921
× 70
= 344,470 *(shift one place left)*
Step 3: Add:
14,763
+ 344,470
=
359,233
✔ Answer: 359,233

Step 3: Add: 1,734 + 20,230 =
21,964
✔ Answer: 21,964
---
🔢 Problem 10: `94 × 48`
Step 1: 94 × 8 = 752
Step 2: 94 × 40 = 3,760

## 📝 Teaching Tip:
The
standard algorithm involves:
- Multiplying each digit of the bottom number by the top number, starting from the right.
- Shifting left for each higher place value (e.g., tens, hundreds).
- Adding all partial products to get the final answer.
This method reinforces place value understanding and is foundational for more advanced math.
