PEMDAS Puzzles is a small site for people who like order-of-operations problems. Five new order-of-operations problems appear every day, and everyone gets the same five on the same date.
Each day's problems are generated from the date by a program. It checks that every problem has one exact answer and at least one tempting wrong answer, usually the result of reading strictly left to right. Every solution shown on the site is produced by the same solver, so the steps always match the answer.
The viral-problem pages are written by hand, and every worked answer is checked by the solver before the site is published. If you think something is wrong, please tell us.
Write to hello@pemdaspuzzles.com. We read everything and fix mistakes quickly.
It is free to use. The site is supported by advertising, and it may earn a small commission from some links. That never changes an answer.
