"Teoremas, Etc." is like stepping into a quirky math class taught by a hopeless romantic. José Madero uses arithmetic vocabulary to confess how his attempts to manipulate feelings backfired: when he aimed to make others cry, he only sparked laughter, and every step forward came with a miscalculated sign. By telling listeners to add everything they know about him, multiply constants or divide fractions, he exposes a life reduced to formulas where the negative value stubbornly checks out.
Beneath the clever wordplay hides a darker admission. He blames substances, resentment, and his own clumsiness for dimming his inner light, and wonders if he should correct the equation or just let the ride finish. The chorus finally pinpoints the missing variable - a little affection. In other words, no matter how many theorems you prove, the heart refuses to be solved without a touch of warmth.
