Happy Tau Day 298
Forget about Pi Day, today we celebrate something twice as good: Tau Day. For far too long, Pi has been the bride and Tau has been the bridesmaid. As Michael Hartl points out in The Tau Manifesto, "Pi is a confusing and unnatural choice for the circle constant." He is giving a talk at the California Institute of Technology based on the Manifesto, with pie served at the end. "Twice as many as you might expect," he says.

Then you teacher failed. Showing your work is about knowing the procedure to do something.
Even the dimmest child can look at: 4 * X = 8 and KNOW X=2. But the real lesson is showing the work so when it's not that easy you can get a correct answer.
You use an easy example so when they finish going through the correct steps they can know they did it correctly.
