---
Wait — this one is tricky. Let's check:
It says:
15 + 1,0090
But 1,0090 is likely a typo. It probably means 1,0090 as 10,090, or maybe 1,0090 is meant to be 1,009 or 10,090?
Looking at formatting:
`15`
`+ 1.0090` ← Wait, it’s written as `1.0090`? But that would be a decimal.
But in context, it's clearly whole numbers, so likely:
It should be 15 + 10,090? Or perhaps 15 + 1,009?
But looking at the image format:
It says:
```
15
+ 1.0090
```
Wait — 1.0090? That seems like a decimal number: 1.0090, which is just 1.009
But adding 15 + 1.009 = 16.009, but the worksheet is about whole numbers up to five digits, so likely a typo.
Alternatively, it might be 15 + 10,090 — but written with a dot instead of comma?
Possibility: The number is 10,090, and the dot is a formatting error.
But if we take it literally:
15 + 1.0090 = 16.0090
But since all other problems are whole numbers, this is likely a mistake.
Another possibility: It's 15 + 10,090 — meaning 10,090.
But written as "1.0090" — maybe a misformatting where 1.0090 is actually 10,090?
Wait — no. 1.0090 is 1.009.
But perhaps it's 10,090 and the dot is a typo for a comma.
Alternatively, maybe it's 15 + 1,009? But that would be written as 1,009, not 1.0090.
Let’s look again:
The last problem is:
```
15
+ 1.0090
```
This is ambiguous. But 1.0090 is just 1.009, so:
15 + 1.009 = 16.009
But that doesn't fit the pattern.
Alternatively, maybe it's 15 + 10,090, and the dot is a separator?
Wait — in some countries, dot is used as a thousands separator.
So 1.0090 could mean 1,0090 → but that’s not standard.
Alternatively, maybe it's 15 + 10,090, and the 1.0090 is a typo for 10,090?
But 10,090 is ten thousand ninety, and 1.0090 is not that.
Wait — another idea: Perhaps it's 15 + 1,009? But written as 1.0090 due to formatting?
But 1.0090 is 1.009, not 1,009.
Unless the dot is meant to be a comma, and 1.0090 is 1,0090 → 10,090?
That makes sense: In some regions, dot is used as a thousands separator.
So 1.0090 = 1,0090 = 10,090
Then:
15 + 10,090 = 10,105
That fits the pattern.
So assuming 1.0090 is 10,090, then:
Answer: 10,105

> ⚠️ Note: Problem 15 appears to have a formatting issue. If "1.0090" was intended to be 1,0090 (i.e., 10,090), then 15 + 10,090 = 10,105 is correct. Otherwise, if it's truly 1.0090, then the answer is 16.009, but that contradicts the whole-number theme.
Thus, 10,105 is the most reasonable interpretation.
