Were you taught to do vertical multiplication of algebraic expressions?

I never did this when I went to school, but I thought of it recently to help in doing tutoring. I am certainly not the first to come up with this idea Link
It is so much easier to do things this way and much less prone to error. I don’t see why this way is not taught everywhere.
