You best friends loans you $6 so you can
buy and item for school. As you leave
the store, you find a $5 bill in the parking
lot. After you have repaid your friend,
how much of the $5 is yours? Students
should conclude that they would still be
$1 in debt. Inform the class that the
student’s situation can be modeled by the
mathematical sentence -6+5 = -1.
Find the sum: (-9)+8 = -1
