**Multiplying the Numbers in 10's**

To multiply the numbers in 10's, we need to multiply each digit individually and then combine the results. Let's follow the given steps to find the product of the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, and 0.

1. **Start with the first number:** The first number in the given sequence is 1. We'll start by multiplying this number with the next number, which is 2.

- Multiply 1 by 2: 1 * 2 = 2

2. **Multiply the result by the next number:** Now, we'll take the result from the previous step, which is 2, and multiply it by the next number, which is 3.

- Multiply 2 by 3: 2 * 3 = 6

3. **Repeat the process:** We'll continue this process of multiplying the previous result by the next number until we reach the end of the sequence.

- Multiply 6 by 4: 6 * 4 = 24
- Multiply 24 by 5: 24 * 5 = 120
- Multiply 120 by 6: 120 * 6 = 720
- Multiply 720 by 7: 720 * 7 = 5040
- Multiply 5040 by 8: 5040 * 8 = 40320
- Multiply 40320 by 9: 40320 * 9 = 362880
- Multiply 362880 by 0: 362880 * 0 = 0

4. **Combine the results:** Finally, we combine all the results obtained from the multiplication steps.

- The product of the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, and 0 is 0.

Therefore, the product of the numbers in 10's is 0.
