One day the temperature started at -6°F and dropped 16° by the end of the day. What was the temperature at the end of the day?
See a solution process below:
Saying the temperature dropped
Therefore we need to subtract
The temperature at the end of the day was a cold
The temperature starts off at -6°F.
By the end of the day, it dropped by 16°F. This means you have to add the dropped temperature to find the 'end of the day' temperature. By dropping 16°F, we can say that we have to add -16°F to the original temperature.
-6°F + (-16°F) = -22°F
