Here is a question from Osezua Ibhadode. Obviously Osezua has not yet read my response to Taiwo Atinsola.

I want to encourage you to learn to type your questions properly. The equations editor in MS Word is what I use to set all my responses to the class. I also use it in preparing my notes. It is a good practice to start learning . . .
