A simple math problem went viral in 2019 and sparked huge debate online: 8 ÷ 2(2 + 2). The argument centered on how to apply the order of operations (PEMDAS/BODMAS).
Some people say the answer is 16: solve the parentheses first (2 + 2 = 4), then go left to right — 8 ÷ 2 × 4 = 16.
Others argue the answer is 1, treating 2(4) as a single multiplication step: 8 ÷ 8 = 1.
Experts say the equation is ambiguous, meaning both interpretations appear reasonable depending on how it’s written. The debate showed how even simple math can cause major disagreements online.
