    By adding 104+34 and then 228+877, Then adding both of the results and finally subtracting the answer by one of the factors.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Explanation:

    Which will be…

    104+34=138

    228+877=1,105

    Then add them…

    138+1,105=1,243

    Finally, subtract your answer by one of the factors…

    1,243-1,105

    Which will result as 138. Which is also one of the factors you added earlier, that’s basically what your looking fro when checking and subtraction and/or addition problem.
