Rewrite 7 − 8 using the additive inverse and display the new expression on a number line. 7 + (−8) A horizontal number line is shown with labels from negative 8 to positive 8. A blue arrow begins at 0 and ends at 7. A red arrow begins at 7 and ends at negative 1. 7 + 8 A horizontal number line is shown with labels from 0 to 16. A blue arrow begins at 0 and ends at 7. Another blue arrow begins at 7 and ends at 15. 7 − (−8) A horizontal number line is shown with labels from 0 to 16. A blue arrow begins at 0 and ends at 7. Another blue arrow begins at 7 and ends at 15. 8 − 7 A horizontal number line is shown with labels from negative 8 to positive 8. A blue arrow begins at 0 and ends at 8. A red arrow begins at 8 and ends at 1.
