- Aftsoac that 'x' is not prime??..

## aftsoac

verb; acronym

Assume for the sake of a contradiction In math proofs, it is common to start a proof by saying "Assume for the sake of a contradiction that?.." and set about proving a proposition. However, my friend truncated this phrase because he got tired of typing the whole thing. We have been using 'aftsoac' quite frequently ever since, even over telephone conversations (we end up making the 't' silent).

Etymology : acronym: assume for the sake of a contradiction
