You don't get it because you love to stick your nose into other people's business. You come here thinking that you know everything, and keeps criticizing
people because they don't use your LOGICAL methods. 
No-one is interested in your LOGICAL methods. This is the 21st century. We have calculators, in case you don't know, and people are looking to solve math
problems as easily and quickly as they can. They're not going to sit in an exam and spend 1 hour using your LOGICAL way of thinking. They're NOT INTERESTED in
your LOGICAL WAY of solving, so stop criticizing people for using methods that people are familiar with and prefer to use. You even make fun of people
whose 1st language is Not English. Who do you think you are? Just butt out and keep out of other people's business. You know nothing so say nothing!
I'm tired of you old people coming in here and trying to dictate how people should do things.
