basfree5(11) is that weird base system i created that works like this: the first to numbers: 11-143 are like normal bas5 but then from 154 onward until 1210 you add 11 like in bas10. It's called bas free5 bcz it's Quinary but free, any number can exist but it will be still like bas5: like 923 is 9*25, 2*5 and 3. 225+10+3 =238.
