Given statement is "You download 12 new songs to your MP3 player. then you delete 5 old songs."
We have to write each amount as an integer.
Download 12 new songs means you are adding number to your MP3 player so we will use + sign for 12
So the amount in integer form will be +12
Ddelete 5 old songs means you are subtracting number from your MP3 player so we will use - sign for 5
So the amount in integer form will be -5
combining both expressions we can write final statement as:
+12-5
Which can be simplified to +7.
