The first 5 is in the 10s place. The second is in the ones. To write this out, it would be 5 tens (50), plus 5 ones (5); 55. I don't know if this is what you were looking for, but I hope I could help in some way!
Sometimes...
2^-3 = 1/(2^3) = 1/8
-2^-3 = 1/(-2^3) = -1/8
34/32 can also be written as 1.0625 or 1 & 1/16.
