The mathematical evolution of Ed Sheeran's album titles is reaching POLYNOMIAL proportions! Starting with basic arithmetic symbols (+, ×, ÷), his discography has apparently decided to solve for x in 2023 with a quadratic equation. By 2026, we're getting the full quadratic formula solution! If this trend continues, his 2029 album will probably be tensor calculus and by 2035 he'll just name an album after Schrödinger's equation. Musicians becoming mathematicians? It's EXPONENTIAL madness! Next thing you know, Taylor Swift will release "Partial Differential Equations (Taylor's Version)".
