Get the brain thinking...

edited June 8 in General student discussion
... something a bit lighter. This was a twelve year olds maths homework and this even had me scratching my own head, and my kids had to help me complete it!

You have four 4's plus all the symbols + - / x

Starting at 0 and ending at 9, you must use all of the 4's plus any or all of the symbols, more than once where necessary, to get the required number; I've done 0 already;

0 = (4+4)-(4+4)
1 =
2 =
3 =
4 =
5 =
6 =
7 =
8 =
9 =

Each person do one and repost. If you can do all of them, don't post the answers but PM me instead with your time and I'll let you know.

It's not as easy as it looks!

Regards,

Robert

    3 = (4x4)=16-4=12/4=3

    How about ((4-4)*4)+4

    I definitely make that 4 but I'm struggling with 6

    Must be a 24 in there somewhere but how do you get 3 "4"'s to equal 24?

    Excellent, though I think my kids managed to beat all of us! Hilarious to see how many 'oops' peugeot managed to make!

    You can also do it with 3's too, same rule as before, four 3's plus the symbols. I'll start with 9 'cos it's easy;

    9 = (3x3) / (3/3)

    As part of today's work avoidance scheme...

    0 = (3-3)+(3-3)
    1 = (3+3)/(3+3)
    2 = (3/3)+(3/3)
    3 = (3+3+3)/3
    4 = ((3x3)+3)/3
    5 = 3+3-(3/3)
    6 = 3+3+3-3
    7 = 3+3+(3/3)
    8 = 3x3-(3/3)
    9 = (3x3x3)/3

    I was quite relieved, actually.

    I was beginning to get quite stressed over it.

    As no-one had posted anything since Sunday I thought you'd all got tired of it. Anyway, if your brains still need a workout the question is, can it be done with 5s? My feeling is that is can't but prove me wrong.
