38
X 18
Explanation
The given problem is a multiplication problem where 38 is multiplied by 18. When we multiply 8 (the units digit of 38) by 18, we get 144. The 4 is written below the line and the 1 is carried over to the tens place. Then, when we multiply 3 (the tens digit of 38) by 18, we get 54. Adding the carried over 1, we get 55. The 5 is written below the line and the 5 is carried over to the hundreds place. Finally, when we multiply 1 (the hundreds digit of 38) by 18, we get 18. Adding the carried over 5, we get 23. The 23 is written below the line. Therefore, the final answer is 684.

17
X 29
Explanation
The given calculation involves multiplying 17 by 29. To find the product, we multiply the ones digit of 17 (which is 7) by the tens digit of 29 (which is 2), resulting in 14. We write down the 4 and carry over the 1 to the tens place. Next, we multiply the tens digit of 17 (which is 1) by the ones digit of 29 (which is 9), resulting in 9. Adding the carried over 1, we get 10. We write down the 0 and carry over the 1 to the hundreds place. Finally, we multiply the tens digit of 17 by the tens digit of 29, resulting in 20. Adding the carried over 1, we get 21. We write down the entire 21 to the hundreds place. Combining all the results, we get 493.

87 X 40
Explanation
The given question is a multiplication problem where 87 is multiplied by 40. To find the product, we multiply the ones place of 87 with the tens place of 40, which gives us 0. Then, we multiply the tens place of 87 with the ones place of 40, which gives us 0. Finally, we multiply the tens place of 87 with the tens place of 40, which gives us 80. Adding all these results together, we get 0 + 0 + 80 = 80. Therefore, the correct answer is 3480.

32
X 23
Explanation
When multiplying 32 by 23, we first multiply the ones digit of 32 (2) by the ones digit of 23 (3), which equals 6. We write down the 6 in the ones place. Next, we multiply the tens digit of 32 (3) by the ones digit of 23 (3), which equals 9. We write down the 9 in the tens place. Finally, we multiply the ones digit of 32 (2) by the tens digit of 23 (2), which equals 4. We write down the 4 in the hundreds place. Therefore, the product of 32 and 23 is 736.
