Double Digit Multiplication Worksheets - Math Monks - Free Printable

Problem Description:

The task is to solve a series of two-digit multiplication problems. The worksheet contains 16 multiplication problems, and we need to compute the product for each one.

Solution Approach:

We will solve each multiplication problem step by step using the standard algorithm for multiplication. Here's the general process:
1. Multiply the ones digit of the second number by the first number.
2. Multiply the tens digit of the second number by the first number, shifting the result one place to the left.
3. Add the results from steps 1 and 2 to get the final product.

Let's solve each problem:

---

#### Row 1:
1. 66 × 23
- \( 66 \times 3 = 198 \)
- \( 66 \times 20 = 1320 \)
- \( 198 + 1320 = 1518 \)
- Answer: 1518

2. 14 × 47
- \( 14 \times 7 = 98 \)
- \( 14 \times 40 = 560 \)
- \( 98 + 560 = 658 \)
- Answer: 658

3. 87 × 32
- \( 87 \times 2 = 174 \)
- \( 87 \times 30 = 2610 \)
- \( 174 + 2610 = 2784 \)
- Answer: 2784

4. 60 × 48
- \( 60 \times 8 = 480 \)
- \( 60 \times 40 = 2400 \)
- \( 480 + 2400 = 2880 \)
- Answer: 2880

---

#### Row 2:
5. 48 × 21
- \( 48 \times 1 = 48 \)
- \( 48 \times 20 = 960 \)
- \( 48 + 960 = 1008 \)
- Answer: 1008

6. 11 × 71
- \( 11 \times 1 = 11 \)
- \( 11 \times 70 = 770 \)
- \( 11 + 770 = 781 \)
- Answer: 781

7. 36 × 80
- \( 36 \times 0 = 0 \)
- \( 36 \times 80 = 2880 \)
- \( 0 + 2880 = 2880 \)
- Answer: 2880

8. 23 × 42
- \( 23 \times 2 = 46 \)
- \( 23 \times 40 = 920 \)
- \( 46 + 920 = 966 \)
- Answer: 966

---

#### Row 3:
9. 33 × 28
- \( 33 \times 8 = 264 \)
- \( 33 \times 20 = 660 \)
- \( 264 + 660 = 924 \)
- Answer: 924

10. 63 × 27
- \( 63 \times 7 = 441 \)
- \( 63 \times 20 = 1260 \)
- \( 441 + 1260 = 1701 \)
- Answer: 1701

11. 26 × 36
- \( 26 \times 6 = 156 \)
- \( 26 \times 30 = 780 \)
- \( 156 + 780 = 936 \)
- Answer: 936

12. 45 × 25
- \( 45 \times 5 = 225 \)
- \( 45 \times 20 = 900 \)
- \( 225 + 900 = 1125 \)
- Answer: 1125

---

#### Row 4:
13. 24 × 30
- \( 24 \times 0 = 0 \)
- \( 24 \times 30 = 720 \)
- \( 0 + 720 = 720 \)
- Answer: 720

14. 46 × 88
- \( 46 \times 8 = 368 \)
- \( 46 \times 80 = 3680 \)
- \( 368 + 3680 = 4048 \)
- Answer: 4048

15. 92 × 90
- \( 92 \times 0 = 0 \)
- \( 92 \times 90 = 8280 \)
- \( 0 + 8280 = 8280 \)
- Answer: 8280

16. 76 × 67
- \( 76 \times 7 = 532 \)
- \( 76 \times 60 = 4560 \)
- \( 532 + 4560 = 5092 \)
- Answer: 5092
