OpenStudy (anonymous):

yes that is correct

jimthompson5910 (jim_thompson5910):

-7 - 1 is the same as saying -(7 + 1) So you add 7 and 1 to get 8 Then you can make the answer negative to get -8 So -7 - 1 = -8

jimthompson5910 (jim_thompson5910):

You can think of it like this: -7 represents 7 IOUs If you take one dollar away to get -7 - 1, you'll have 8 IOUs, which is represented by -8
