You need to be lazy enough to get to the solution
This math teacher is the person every student currently studying mathematics needs. While it might seem like a bold idea for a teacher to encourage his students to be lazier, the underlying theory behind it made a lot of sense. Because better than cramming large, pre-defined solutions, one can come up with a ‘not-so-perfect’ solution that gets the job done quickly.
Not only will the students learn better, but this type of attitude will lessen the burden of academics. Doing less challenging work is usually neglected nowadays.
