They'll need math to calculate the projectory

They'll also need English to know that the word isn't projectory. It's trajectory. A simple spell check would reject projectory.

Maybe they were estimating the term using EE (everyday English)

To all
Why is public education failing?
I think its because of the concept of “education major”.
It’s an intellectually bankrupt concept and now we are reaping the whirlwind.
Teacher’s need to have demonstrate “mastery” of a legitimate major it doesn’t matter if they end up teaching kindergarten. Of course the self-serving NEA just adds to the problem.
