Understanding the Calculation Error: Why n = 20 → 360° → 360 ÷ 90 = 4 Is Invalid When exploring angles and proportional measurements, common math errors can lead to misleading conclusions. One frequent mistake involves combining unit conversions and proportional reasoning incorrectly—such as the expression n = 20 → 360° → 360 ÷ 90 = 4—which appears logical at a glance but fails crucial mathematical steps. This article explains why this derivation is invalid and how to approach angle calculations correctly. --- ### Breaking Down the Misleading Equation
