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?
Adding is the opposite of subtracting
The opposite form of 'expendable' with a prefix added is 'inexpendable.'
It is the same as adding the opposite. 1 - 1 = 1 + (-1 ) = 0 1 - 5 = 1 + (-5) = -4
as adding a ".... in the opposite direction.
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.
