Turn it through 180 degrees
You will add -3 to 9 to make it 6.
3 + 6 + 9/9
abs(4 - 9) * 6 - 6 or, equivalently, (9 - 4)*6 - 6
9 x ( 6/9 + 2 ) = 24
(6/6)+(6/6)+(6/6)+6=9
we will add -3 :)
9+(-3)=6 6-(-3)=9
(9*9)+(9+9)+(9/9) = 100
By arranging the digits, you can make 1699, 1969, 1996, 6199, 6919, 6991, 9169, 9196, 9619, 9691, 9916 and 9961. But there are a lot more that you can "make", such as 9*9 + 6 + 1 = 88 or 9^6 + 9 + 1 = 531,451.
6 +[(6 x 6) / (6 + 6)] = 6 + 36/12 = 6 + 3 = 9
(2*9)+(6*1)=24
(9 - 1) * 6 / 2 = 24.
