    All righty idk where to put this thread so i decided to put it here.

    So my math teacher tells us to

    -Use four 4s and come up with ways to end up with numbers 0-5 then he said for homework get 6-20

    Ex. (4+4)-4)-4=0 4/4+4/4=1

    (Get the picture)

    So ive done 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 19 20

    i need DONE

    Ive spent over 2 hours on this and i got no clue..and its gettin late so can somebody(ies) help me

    You can use any method possible like 4^4 or |4| or -4. oh and numbers like 44 count as 2 4s and 4444 would count as four 4s.
    -thanks

    But don't you only need numbers up to five? I did this today also but I only got to use 1,2,4,5 once the same way. I'll try to help.
