What is the quotient of the opposite of 30 and 6, plus the opposite of 8

Let's pull it apart ...

The quotient of the opposite of 30 and 6

The opposite of 30 is - 30 and the quotient of - 30 and 6 means - 30 divided by 6 or

-30/6 = - 5

Now the other part ...

Plus the opposite of 8. The opposite of 8 is - 8, so plus - 8 just means minus 8 or - 8. So we have the first part added to the second part ...

-5 + (-8) which can also be written - 5 - 8

-5 - 8 = - 13
