Place it right after the wrong answer appears, as the first reaction in the edit, then follow it with Bruh for a flat acknowledgement of the mistake. If the fail needs a bigger finish, add Emotional Damage Meme afterwards, so the sequence moves from the maths slip to a flat reaction and then to a bigger finish.

Igreg Maths is a very short meme clip, lasting under a second, built around a playful maths theme. Its abrupt delivery lands as a quick absurd joke rather than a full line, giving listeners a brief flash of confusion followed by a laugh. It works as a tiny reaction, because its humour comes from how little it explains and how fast it disappears.
