    LakeMountD,

    "can you please tell me how you got this? explain what you did?"

    No, but I'll give you some hints.

    What's the highest digit in any of the numbers (including my answer)?

    8, what does that have to do with anything?

    LakeMountD,

    "8, what does that have to do with anything?"

    A lot. If I made up a list of a million more addition problems like the one you asked about, the highest digit in all of them would be 8 too.

    A hint: What might have happened (in math) if people all had six fingers or 8 fingers instead of 10 fingers?
