Final answer:
To solve 102 * 4, multiply 4 by 2 (units digit), then multiply 4 by 100 (hundred's place), add the results to get 400 + 8, which equals 408.
Step-by-step explanation:
The question involves a basic multiplication problem, which is carried out step by step to reach the final product. Let's solve 102 * 4 using the given steps:
- 4 X 2
- 4 X ( 100+2)
- 400+ 8
- 408
Here's how we got there:
- First, we multiply 4 by the units digit of 102, which is 2. So 4 * 2 = 8.
- Next, we distribute 4 into the sum of 100 and 2, giving us (4 * 100) + (4 * 2).
- We then complete the multiplication to get 400 + 8.
- Finally, we add those results together to get 408, which is the final answer.
