12 ADDITION CHARTS | Tables 1 to 12

Twelve addition charts are indicated by the file's title, cover page ('ADDITION TABLES, 1 TO 12'), and page count, with each of six extracted sections showing two rows of header numbers running 1 through 10. Because the actual addition-table grids — the sums themselves — are rendered as images or graphics rather than extractable text, this record cannot verify the specific addition facts each chart displays or how many charts appear per page. The extracted header rows show numbers only up to 10, not 12, so the 'tables 1 to 12' claim in the title could not be confirmed from this evidence.
