Guest Posted December 1, 2007 Report Share Posted December 1, 2007 not for nothin...if u turn two sevens upside down next to two sevens downside up it forms two slanted zeros...with a one in front of it = 1 L7 L7]...what do ya think? Link to comment Share on other sites More sharing options...
Guest Posted January 2, 2008 Report Share Posted January 2, 2008 not to over simplify but woudn't 177-77 do it? Link to comment Share on other sites More sharing options...
Guest Posted January 11, 2008 Report Share Posted January 11, 2008 ( 7 * 7 ) * 1 = 100 (7) (7) ^ | base 7 Link to comment Share on other sites More sharing options...

This was the first solution I thought of. The second was the 177-77=100 Link to comment Share on other sites More sharing options...
Guest Posted February 17, 2008 Report Share Posted February 17, 2008 this would work if you can have indicies (which is a mathmatical symbol) 7^2+7^2+(7/7)+1 works for me (the ^2 is squared btw) Link to comment Share on other sites More sharing options...
Guest Posted February 17, 2008 Report Share Posted February 17, 2008 might have another here 7^3= 343 343/(1+7/7)^2=343/4=85.75 85.75+7+7= 100 to 1 d.p. so... (7^3)/(1+7/7)^2+7+7 =100 to 1 d.p. but thats 7 sevens Link to comment Share on other sites More sharing options...
Guest Posted April 15, 2008 Report Share Posted April 15, 2008 Yes, real simple......... ( (7x7) + (7x7) ) + 1 = 100 Link to comment Share on other sites More sharing options...
Guest Posted April 18, 2008 Report Share Posted April 18, 2008 (edited) 177-77 or, since no one hit it yet -77 + 177 Edited April 18, 2008 by TySim Link to comment Share on other sites More sharing options...

Except (Edit: In addition to) the five numerals you can use the usual mathematical operations +, -, x, :, root and brackets (). Reveal hidden contents 100 - solution 100 = 177-77 = (7+7)x(7+(1:7)) I do not know other solutions. The number 100 already exists. I can't create it.

Guest Posted July 1, 2008 Report Share Posted July 1, 2008 (7*(7+7)) = 98 + root7 = 100.64... - 1 = 99.64... = 100(3sf) Link to comment Share on other sites More sharing options...

Good try though, I can't get one yet. lol Link to comment Share on other sites More sharing options...

Guest Posted October 17, 2008 Report Share Posted October 17, 2008 Piece of cake 7 squared + 7 squared +1 +7/7=100 49+49+1+1=100 Link to comment Share on other sites More sharing options...
Guest Posted October 23, 2008 Report Share Posted October 23, 2008 My answer is: (7²+1)((7+7)/7) = 100 (49+1)(14/2) = 100 50x2 = 100 I thought inverting the 7's was sheer genius Link to comment Share on other sites More sharing options...
