To find the current temperature, we need to subtract the change in temperature from the original temperature:
Original temperature: 26 degrees Celsius
Change in temperature: -15.5 degrees Celsius
Current temperature = Original temperature + Change in temperature
Current temperature = 26 + (-15.5)
Current temperature = 26 - 15.5
Current temperature = 10.5 degrees Celsius
The temperature now is 10.5 degrees C.
