Hhhh

A stick-figure character in a tie stands beside a whiteboard with "2+2=" written on it, then the scene cuts to a close-up of another character screaming, followed by a character in a cap sitting on a chair, then the first character appears upside down on the whiteboard with "+8=" written on it, then the character in the cap is shown sitting at a desk, and finally the character in the tie holds a knife with a determined expression. The setting is a simple, white background with minimal detail.
