According to "The Mathematical Experience", by Davis and Hersh, page 334,
"Russell and Whitehead ... after 362 pages, the arithmetic proposition
1+1=2 is established." and they show part of that page which says "From
this proposition it will follow, when arithmetical addition has been
defined, that 1+1=2."
