However, it is not obvious how one should extend this version of addition to include fractional numbers or negative numbers. A translation by 2 followed by a translation by 4 is the same as a translation by 6. A translation by 4 is equivalent to four translations by 1.

A second interpretation of addition comes from extending an initial length by a given length: When an original length is extended by a given amount, the final length is the sum of the original length and the length of the extension. The unary view is also useful when discussing subtractionbecause each unary addition operation has an inverse unary subtraction operation, and vice versa.

Now I understand that I can't have more than two carries. I have another question for you: Can I do the multiplication this way?

In the octal one you accidentally got the wrong answer for your multiplication. Here is the answer I got: It doesn't, so you get: It works for me but it may not seem like a good way to you: In order to multiply bases other than 10 and 2, what you need to do is something in relation to base In the end, you need to check your work.
