Question
The temperature is measured five times.The first temperature measured is 7 °C.The temperature goes down by 13 °C, up by 4 °C, down by 9 °C, and then up by 1°C.What is the final temperature measured?
Solution
The first temperature measured is 7 °C.
The temperature then goes down by 13 °C. So, 7 - 13 = -6 °C.
Then, the temperature goes up by 4 °C. So, -6 + 4 = -2 °C.
Next, the temperature goes down by 9 °C. So, -2 - 9 = -11 °C.
Finally, the temperature goes up by 1 °C. So, -11 + 1 = -10 °C.
So, the final temperature measured is -10 °C.
