The result of adding and integer and its opposite is negation. A + (-A) = 0 For all real integers. It has the effect of adding 0 to a sum. Example: 32 + 16 + (-16) + 5 = 37 = 32 + 0 + 5.
adding its opposite?
It is the same as adding the opposite. 1 - 1 = 1 + (-1 ) = 0 1 - 5 = 1 + (-5) = -4
Adding is the opposite of subtracting
The opposite form of 'expendable' with a prefix added is 'inexpendable.'
Unoriginal.
Well I believe you may be referring to the fact that whenever you subtract you actually "add the opposite." Another phrase people may use is to "plus a negative." This is not as accurate as add the opposite. An example would 12-5. It can be written as 12 + -5. You are simply adding the opposite of positive 5 which is negative 5. Now this may seem silly, but where it is useful is when you have a lot of negatives. For example. -10- -5. For some this is confusing until we add the opposite. I can rewrite this as -10 + 5. I simply took the opposite of -5 which was positive 5 and added it to -10. This equals -5. Hope this helps.
This means that, for example: 15 - 5 = 15 + (-5) 15 - (-5) = 15 + 5 Knowing this relationship can both help you do the actual calculations, and assist you in solving equations.

The opposite of 30 is -30, and the opposite of 8 is -8. The quotient of -30 and 6 is -5. Adding this to -8 gives us -13. Therefore, the final answer is -13.
Adding the prefix "in" to a word often indicates negation or the opposite meaning. For example, adding "in" to the word "visible" creates "invisible," meaning not able to be seen. This prefix can change the meaning of a word to its opposite.
It is the same as adding a positive and adding a negative number
