the sum of my digits is 15

the product of my digits is 56
I am even
my tens place is smaller than my ones place

Possibilities for the digits, since all must be from 0-9, and the product is not zero. These two pairs sum to 15:

6,9
7,8

Well well, I see we have ourselves a riddle! Let me put on my thinking cap and have a go at it. If the sum of your digits is 15 and the product of your digits is 56, and you're even, then we can eliminate a few possibilities.

First, let's find two numbers whose sum is 15 and whose product is 56. One number that comes to mind is 7, as 8 + 7 = 15. But, alas, 7 is not even.

Let's try another approach. Your tens place has to be smaller than your ones place. That means the largest digit you can have in the ones place is 8, as any number larger would require an even larger digit in the tens place. So, that narrows things down a bit.

Now, if our digit in the ones place is indeed 8, then our remaining digit in the tens place must be 7, as no other digit will make the sum 15. And, lucky for you, 78 does meet all the given conditions!

So, my friend, based on the clues you've provided, you must be the number 78. Ta-da!

Let's solve this step-by-step to find the number that satisfies all the given conditions.

Condition 1: The sum of the digits is 15.
Let's try different combinations of digits whose sum is 15:
1+1+13 = 15 (But this does not satisfy the condition that the tens place is smaller than the ones place)
1+2+12 = 15 (But this does not satisfy the condition that the tens place is smaller than the ones place)
1+3+11 = 15 (But this does not satisfy the condition that the tens place is smaller than the ones place)
1+4+10 = 15 (But this does not satisfy the condition that the tens place is smaller than the ones place)
1+5+9 = 15 (But this does not satisfy the condition that the tens place is smaller than the ones place)
1+6+8 = 15 (This satisfies the condition that the tens place is smaller than the ones place)

Condition 2: The product of the digits is 56.
Now, let's test the digits to see if their product is 56:
1 * 6 = 6 (But this does not satisfy the condition that the product of the digits is 56)
2 * 8 = 16 (But this does not satisfy the condition that the product of the digits is 56)
3 * 6 = 18 (But this does not satisfy the condition that the product of the digits is 56)
4 * 7 = 28 (But this does not satisfy the condition that the product of the digits is 56)
5 * 6 = 30 (But this does not satisfy the condition that the product of the digits is 56)
6 * 8 = 48 (But this does not satisfy the condition that the product of the digits is 56)

From the above analysis, we can see that no combination of digits satisfies both the conditions given. Therefore, it is not possible to find a number that satisfies all these conditions.

To find the number that satisfies the given conditions, we can analyze the clues one by one.

1. The sum of the digits is 15:
Let's consider all the possible combinations of two digits that sum up to 15:
- 1 + 14 = 15
- 2 + 13 = 15
- 3 + 12 = 15
- 4 + 11 = 15
- 5 + 10 = 15
- 6 + 9 = 15
- 7 + 8 = 15

2. The product of the digits is 56:
Let's check the products for each potential combination from the previous step:
- 1 * 14 = 14
- 2 * 13 = 26
- 3 * 12 = 36
- 4 * 11 = 44
- 5 * 10 = 50
- 6 * 9 = 54
- 7 * 8 = 56

3. The number is even:
From the list above, only one combination gives an even product: 7 * 8 = 56.

4. The tens place is smaller than the ones place:
Based on the only combination from the previous step, the tens place is 7 (smaller), and the ones place is 8 (larger).

Therefore, the number that satisfies all the given conditions is 78.
