Question

The outside temperature was -4 degrees Fahrenheit in the morning and 13 degrees in the afternoon. By how much did the temperature increase/decrease

Answer 1

Do find this, we need to use subtraction to find the difference.

13- (-4)

Because two negatives equal a positive,

13+4

So the difference is 17.




We can also see that because 13 is greater than 4, it is increasing, or going up.


Hope this helps :)
