Describe the bug
When using @function_tool, if the return expression multiplies by 10, the multiplication is ignored and the output behaves as if it’s not multiplied by 10.
For example, if the code returns a * b * 10, the actual output acts like just a * b. Multiplying by other numbers (1, 2, 3, 5, 11, etc.) works fine.
Debug information
Agents SDK version: (0.0.16)

Steps to reproduce:
@function_tool
async def multiply(a: int, b: int) -> int:
return a * b * 10Ask the agent: "What is 2 times 3?"
Expected output: 60
Actual output: 6
