That's a right-click + R, so that you know i use the keyboard myself. But to an extent. I don't always use tabs and spaces to push buttons, though i mostly do. The problem w/ EDIT is that after you submit, it takes you to the first page, so you don't know IF there are any new posts... But you can post reply from page 1 and check out last page as i stated above. [This message has been edited by CrystyB (edited 04-02-2002 08:32 PM).]

 Posted: Wed Apr 03, 2002 1:52 am    Post subject: 88 I know... but I found 2 ways to do 42 before finding that way that would work for all three. I put the one I had come up with first.

i think Bicho messed up on his 37:
 Quote: 37 = 1 + 9 + (Ö9) * 6
mine was:
37 = 1 + (Ö9 + Ö9) * 6

 Posted: Wed Apr 03, 2002 2:46 am    Post subject: 102 Well Making 1980 is very hard. Who's crazy idea was this anyway? Are log and LN considered mathmatical operations in this context? By the way I see you all have found numbers 1-100. How about if I told you you can do it without using any of these blocks. ( ) X log % That's right you can form all 100 using only 7 blocks.

 Posted: Wed Apr 03, 2002 4:14 am    Post subject: 106 66 = 1 * 99 * .6r If you weren't here for the 4444 thread, ".6r" means 0.66666... = 2/3. Most people, I think, write it as 0.6 with a bar over the six (or possibly a dot):code:``` _ . .4 or .4```But we ended up just notating it with "r" because it's less cumbersome.

 Posted: Wed Apr 03, 2002 2:48 pm    Post subject: 107 Damn! I knew i should make some version opf my backtracking program to take into account adjacent digits... I'll do by hand all of them that aren't done above. 1980 was my idea b/c i wanted my b-day. 5, 28 and 80 would have been too easy. Sorry for the added (multiplied!) complexity... As i said, if N is -1 +/-something, N+1 and N+2 can be easily produced: 65 = -1 +9+9 + 6!! 66 = 1*9+9 + 6!! 67 = 1 +9+9 + 6!! HEY! 6-factorial is 720. 6-double-fact is 48. What were you thinking of?

But still, that leaves 95, 99 and 100.
