Addition
Here's a question I've come across and I am stuck...
The questions goes like this (even though there are no six in the question which puzzles me)
Replace as many of the digits 5, 6, 7, 8 with a zero as are necessary to make this addition correct.
555
777
888
999+
___
1111
This is my attempt. I guess, 9 cannot be made zeros, (as question doesn't mention it) so I did this but it's not correct.
005
007
000
999+
___
1111
Any help would be very much appreciated... Thanks :)

Re: Addition
Hey Natasha1.
Can you replace anything with a zero? If so why is your answer wrong?

Re: Addition
Because it does not make 1111 what I did.
The question is this Replace as many of the digits 5, 6, 7, 8 with a zero as are necessary to make this addition correct. (but what I don't get is that there are no 6 in the addition given and we are not told we are allowed to touch the 9)
So I am stuck...

Re: Addition
Sorry: for some reason I thought it was OK (just having a bad day).
Try this:
055
077
880
099
___
1111

Re: Addition
Assuming we are allowed to change a 9, which is not mentioned in the question then that would work. Thanks for your help!
