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

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 :)

What are the options
