Negation Memes

A brilliant progression of mathematical operators disguised as everyday items: 1. Step ladder = "raise to power" (exponentiation) 2. Compass = "direction" (vector) 3. No entry sign = "not" (logical negation) 4. Guitar pick + village = "pick a village" (selection operator) The difficulty escalation is spot on. Started with basic exponents, ended with selection operators. Just another day of mathematicians turning ordinary objects into symbols that will eventually make undergrads cry during finals week.
