I am trying to figure out how to add negadecimal numbers by hand.
I can add normal decimal numbers using an algorithm I learned in kindergarten: start with the least significant digits, add them, carry, move left, repeat.
Carry: 1111 1 First: 156739 Second: 948352 ======= 1105091
The same algorithm, however, yields incorrect results when trying to add negadecimal numbers.
If I add these two negadecimal numbers together, this should be the result:
First: 156739 Second: 948352 ======== 19083071
but I am not sure what algorithm I can use to achieve this result. How can I add two negadecimal numbers?
