Could anyone explain to be what these term mean in math? I try googling them but can't find the answer. Thanks

1.Opposite of a Difference
2.Opposite of a Sum
3.Opposite of an Opposite

  • Math -

    The opposite of a number is its additive inverse. I do not see the term opposite used very frequently in this sense in English, although this is the proper term in French (l'opposé).

    For example, the opposite (or additive inverse) of 4 is -4.

    You can check the validity by adding the two numbers together. Any number added to its opposite should give zero.
    Since 4+(-4)=0, we can safely say that the opposite of 4 is -4.

    With the definition above, you should be able to handle the question. Post if you need more information.
