Very good! Nice and easy, but fun. I tried this one on my brother just now, and he made a drawing of the the three nines flipped around and mashed together, and it sort of looked like an 8. HAHA! I had to give him credit for creativity.
haha that was a good one!
not bad not bad at all good actually very nice
thanks to all of you
Thats funny! I totally didn't get it at first, but after a while it just hit me. I really liked it
good one.
I got 9 (squared) minus 9 divided by 9, which also works (depending if you count the squared as 2 nines, though i think its only 1).
81 - 9 = 72, 72/9 = 8.
But good teaser
81 - 9 = 72, 72/9 = 8.
But good teaser
Actually, jezza, you were supposed to only use ninesto get the answer, although that was good thinking. I never thought of that.
Depending if you count the squared sign as a number or mathematical sign, then it was only 9's.
(9 (sqr) - 9)/9 = 8.
hehe, but your answer is better, more accurate and more fun. Just thought id throw mine in there
(9 (sqr) - 9)/9 = 8.
hehe, but your answer is better, more accurate and more fun. Just thought id throw mine in there
i guess if you look at it that way, it could be correct too.
OK...but how about "three 9s" equals 8 keystrokes...that works too
yeah, that works, too.
jezza - that is four nines equal 8
[(9X9)-9]/9 = 8
[(9X9)-9]/9 = 8
A fun way to show how to mess with numbers!
Shouldn't this be in math?
