Overview
- El Comercio published a new timed puzzle on Tuesday that presents (15+9)×2÷6−3 and shows the step-by-step PEMDAS solution as 5.
- The day before, the paper ran a similar timed challenge—56÷(9−2)+6×3−4—with a worked solution that yields 22.
- Each item appears in the magazine/lifestyle section and gives a full, paced explanation of each arithmetic step plus links for more practice.
- Both articles explicitly teach the PEMDAS rule (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction) and apply it in order to reach the published answers.
- The pieces are framed as light entertainment and cognitive training for broad ages, recommending that teachers and families adapt difficulty and use the exercises to build mental agility.
