# Add an extra, then remove it · complete text alternative


## Role

Adult ordinary model; exposed solution separate from genuine blank own work

## Complete source

Day 53 ordinary 398+267 sticker source.

## Full alternative

An adult exact-compensation model. Fictional 398 and 267 stickers total 665. Replacing 398 with 400 adds two extra, gives 667, then removing those extra two yields 665. A separate estimate 400+300≈700 checks scale; it is not the exact total.
