With a bit of imagination, anything is possible. I tried it myself for two seconds before looking it up.

You not only arrange three nines, but you also introduce a bit of mathematical notation (a plus sign, a ratio, and a decimal point).
The answer is (9+9)/.9
In adding 9 and 9 you get 18. You then divide it by .9 (or 9/10).
18/(9/10) = (18*10)/9 = 180/9 or 2*10 = 20
Or you could just pop it into a calculator and get 20 that way.
When I first saw the question, I thought you wanted the numbers to look like '20'.
With a bit of imagination, anything is possible. After all, 9+9=21.
Three cubed minus three equals twenty four.
the purpose is that poo is used to make houses
three twenty five cents, and three one cents
9 / 9 + 9 = 10.
99 divided by 0.99
99/9=11
Three cubed minus three equals twenty four.
(3+3) / .3
Chromosomes are what make up your DNA. YOU ORIGINALLY HAVE FORTY SIX CHROMOSOMES TWENTY THREE FROM YOUR MOM AND TWENTY THREE FROM YOUR DAD THATS WHERE YOU GET THERE GENES AND THEIR CHARACTERISTICS!
You can't change the time on Howrse.
18 5+18=23
twenty three pound a day
the purpose is that poo is used to make houses
999 + 9/9 = 1000
three twenty five cents, and three one cents
99 + 9(9-9)
9 / 9 + 9 = 10.
