I write about doing ordinal arithmetic with the Cantor normal form, which is an ordinal denotation system, as powerful and useful for the ordinals as the decimal number system is for ordinary numbers.

A certain fortuitous cancellation phenomenon often occurs when adding ordinals in their Cantor normal form—entire groups of terms can sometimes simply disappear, having been conveniently absorbed into a larger term on their right.
