  • Its powers of 5. Thats simple.

  • @Froppindroppin Nope!

  • I have just seen the solution, it's a nice "trick" but its not correct :(

    First I have to say that 1 cant be mathematicly 5 so we avoid maths, that means when u say 1 = 5 ..... 5 doesnt have to be 1 because WE AVOID MATHS ...

    Let me explain by an example :

    First u say an apple is a fruit (1=5)

    Then u say all fruits are apples ....? (5=1) ?? I think NOT !

    But its a nice trick for people who cant think logically :)

  • @phtmexplo 1 can be 5, for example in modular arithmetics. And the "=" sign is commutative.

    Anyway, I start the problem with an "if", don't I? ;-)

  • is it 3092?

  • @DOminik962 Check the solution!

see all
