6128 + 9091 = 9825

8159 + 1912 = ?

hi, this is my first posting as a new member, but my question is whether we are supposed to redefine the operator "+", the numbers, or both?

because if by "+" you mean, "add these two numbers together and subtract 5,394," then it's probably too easy right? Can you give another example of an equation that would restrict the rule a little more, without making the pattern too obvious?

just a thought.

Hi Math Student, and welcome to the Den <ahttp://brainden.com/forum/uploads/emoticons/default_cool.png' alt='B))'>

  1. The numbers do, in some manner, get "redefined".
  2. "+" has its normal meaning. It should not be redefined
  3. Can I give another example without making the pattern too obvious?
    The answer is yes. But it would take me a few minutes to think of one.
    I could think of several quite quickly that would pretty much give it away.
    Those statements do convey a clue.

thanks for the welcome, bonanova, and for addressing my questions!

apparently, i hadn't toggled my reply to accept email notifications of replies, and i don't check often enough yet. so i apologize for the delay.

but i see how if you rotate the numbers that are to the left of the equal sign by 180 degrees upside down... places get inverted, sixes become nines, twos stay twos and five stay fives (at least in a funky font :P )

very cool.
