Overview
- Multiple Argentine outlets published short explainers on Wednesday that turned viral mixed‑operation puzzles from social media into step‑by‑step challenges for readers.
- The pieces uniformly taught the standard order of operations—parentheses, exponents, multiplication and division left to right, then addition and subtraction left to right—to correct common mistakes.
- Each article gave concrete worked answers to viral examples, including (40×2+20)÷(25+25)=2, 70+7×3÷3−7=70, 20+20÷5×3=32 and 125−25÷5×7=90.
- Reports said many online respondents answered these problems incorrectly, and outlets used that public confusion as a reason to republish clear solution steps.
- The coverage framed solving these puzzles as cognitive practice and cited neuroscience work and experts to support benefits for concentration and decision making while noting this is educational repackaging rather than new scientific findings.
