In base 2.5
10 (base 2.5) = 2.5 (base 10) 2 + 1 (base 2.5) = 10 (base 2.5) + .5(base 10) 2.5^(1) = .4 (decimal) 10.1 (base 2.5) = 2.9 (base 10) 2.5^(2) = .16 OK, I goofed up. 10.11 (base 2.5) is too big for 2+1. That'll teach me to try doing this in my head. It's hard for me to think in a nonnatural number baseit isn't natural.
base 2.5 to base 10 pairs 1 = 1 10 = 2.5 100 = 6.25 1000 = 15.625 0.1 = .4 0.01 = .16 0.001 = .064
