A contrapositive is a statement that negates and interchanges the hypothesis and conclusion of a conditional statement.
Conditonal Statement:
If I go to work, the roads are clear.
Contrapositive (Of the conditional statement):
If the roads are not clear, I will not go to work
To form that contrapositive I negated both the hypothesis and conclusion, and then interchanged them.

-7 + 14
7
