Multiplication practice worksheet with 16 problems for students to solve.

Problem Description:

The task involves solving a series of multiplication problems. Each row contains four multiplication expressions, and the goal is to compute the product for each expression.

Solution Approach:

We will solve each multiplication problem step by step. Here are the steps for each calculation:

---

#### Row 1:
1. 528 × 10
- Multiplying any number by 10 simply adds a zero at the end of the number.
- \( 528 \times 10 = 5280 \)

2. 312 × 23
- Perform long multiplication:
```
312
× 23
------
936 (312 × 3)
624 (312 × 20, shifted one position to the left)
------
7176
```
- \( 312 \times 23 = 7176 \)

3. 653 × 51
- Perform long multiplication:
```
653
× 51
------
653 (653 × 1)
3265 (653 × 50, shifted one position to the left)
------
33203
```
- \( 653 \times 51 = 33203 \)

4. 284 × 42
- Perform long multiplication:
```
284
× 42
------
568 (284 × 2)
1136 (284 × 40, shifted one position to the left)
------
11928
```
- \( 284 \times 42 = 11928 \)

---

#### Row 2:
1. 703 × 80
- Multiplying by 80 is the same as multiplying by 8 and then adding a zero at the end.
- \( 703 \times 8 = 5624 \)
- \( 703 \times 80 = 56240 \)

2. 496 × 18
- Perform long multiplication:
```
496
× 18
------
3968 (496 × 8)
496 (496 × 10, shifted one position to the left)
------
8928
```
- \( 496 \times 18 = 8928 \)

3. 156 × 36
- Perform long multiplication:
```
156
× 36
------
936 (156 × 6)
468 (156 × 30, shifted one position to the left)
------
5616
```
- \( 156 \times 36 = 5616 \)

4. 830 × 93
- Perform long multiplication:
```
830
× 93
------
2490 (830 × 3)
7470 (830 × 90, shifted one position to the left)
------
77190
```
- \( 830 \times 93 = 77190 \)

---

#### Row 3:
1. 145 × 8
- Perform multiplication:
```
145
× 8
------
1160
```
- \( 145 \times 8 = 1160 \)

2. 396 × 5
- Perform multiplication:
```
396
× 5
------
1980
```
- \( 396 \times 5 = 1980 \)

3. 276 × 3
- Perform multiplication:
```
276
× 3
------
828
```
- \( 276 \times 3 = 828 \)

4. 970 × 4
- Perform multiplication:
```
970
× 4
------
3880
```
- \( 970 \times 4 = 3880 \)

---

#### Row 4:
1. 482 × 7
- Perform multiplication:
```
482
× 7
------
3374
```
- \( 482 \times 7 = 3374 \)

2. 806 × 4
- Perform multiplication:
```
806
× 4
------
3224
```
- \( 806 \times 4 = 3224 \)

3. 219 × 3
- Perform multiplication:
```
219
× 3
------
657
```
- \( 219 \times 3 = 657 \)

4. 734 × 5
- Perform multiplication:
```
734
× 5
------
3670
```
- \( 734 \times 5 = 3670 \)

---

Final Answers:

Combining all the results, we get:

- Row 1: \( 5280, 7176, 33203, 11928 \)
- Row 2: \( 56240, 8928, 5616, 77190 \)
- Row 3: \( 1160, 1980, 828, 3880 \)
- Row 4: \( 3374, 3224, 657, 3670 \)

Thus, the final answer is:

\[
\boxed{
\begin{array}{cccc}
5280 & 7176 & 33203 & 11928 \\
56240 & 8928 & 5616 & 77190 \\
1160 & 1980 & 828 & 3880 \\
3374 & 3224 & 657 & 3670 \\
\end{array}
}
