Any time that a negative number is being multipled by another negative number, it equals a positive number. In this case, -1 multiplied by -1 equals 1. Another example of this is -5 multiplied by -5 which equals 25. Though if you multiply a negative by a positve, it equals a negative. If you were to multiply a positive by a positve, it will always equal a positve.
