Guest Posted March 28, 2008 Report Share Posted March 28, 2008 (edited) There was something similar,but I think is not the same.Make both sides equal,to be equation: 1 2 3 4 = 28 2 3 4 5 = 28 3 4 5 6 = 28 4 5 6 7 = 28 5 6 7 8 = 28 6 7 8 9 = 28 You can use all the operations-multiplication ,division, addition,,subtraction... plus brackets,but each digit only ones.

(-1 + (2 ^ 3)) * 4 = 28 (2 ^ 3) + (4 * 5) = 28 Quote Link to comment Share on other sites More sharing options...
0 grey cells Posted March 28, 2008 Report Share Posted March 28, 2008 Can the position of numbers be changed? Quote Link to comment Share on other sites More sharing options...

0 Guest Posted March 28, 2008 Report Share Posted March 28, 2008 3+4+5-6=-2+8 You didn't say that the 28 couldn't be split! Quote Link to comment Share on other sites More sharing options...
0 Guest Posted March 28, 2008 Report Share Posted March 28, 2008 I've got 3 of them 1+23+4 = 28 (2^3)+(4*5) = 28 ? 4*(-5+6)*7=28 Quote Link to comment Share on other sites More sharing options...
0 Guest Posted March 28, 2008 Report Share Posted March 28, 2008 (1+(2*3))+4 = 28 (courtesy to 'grey cells') 4*((5*2)-3)) = 28 4*(5 + 6/3) = 28 (4*7)*(6-5) = 28 Quote Link to comment Share on other sites More sharing options...

I think each digit can be used once suggests the position of the numbers can be changed. Quote Link to comment Share on other sites More sharing options...
0 grey cells Posted March 28, 2008 Report Share Posted March 28, 2008 I think each digit can be used once suggests the position of the numbers can be changed. That was the way I too reasoned . Without repositioning I could not arrive at the result. Quote Link to comment Share on other sites More sharing options...
0 Guest Posted March 29, 2008 Report Share Posted March 29, 2008 Can the position of numbers be changed? Sorry for the delay.Yes.To 3 of them I can't do it without to change the position.If somebody can do it without to change it I would like to see how.

Question
Guest
There was something similar,but I think is not the same.Make both sides equal,to be equation:
1 2 3 4 = 28
2 3 4 5 = 28
3 4 5 6 = 28
4 5 6 7 = 28
5 6 7 8 = 28
6 7 8 9 = 28
You can use all the operations-multiplication ,division, addition,,subtraction... plus brackets,but each digit only ones.
