Using only three 9's along with elementary math symbols like + or -, see if you can arrange them to represent the number 20. Remeber that 99/9=11.

How about [tex]4+4+\frac{4}{\sqrt{4}}[/tex]Njorl said:I had to use one "44". Is there a way to get 10 without resorting to this?

1 1 1 = 6
2 2 2 = 6
3 3 3 = 6
4 4 4 = 6
5 5 5 = 6
6 6 6 = 6
7 7 7 = 6
8 8 8 = 6
9 9 9 = 6
I think using a square root implicity requires a "2".Grizzlycomet said:How about [tex]4+4+\frac{4}{\sqrt{4}}[/tex]
