... all the technology in the world does not justify a person with an average education not to be able to ADD and SUBTRACT!

I am VERY pro-technology. I understand computers are a needed thing..... but not to the point that they allow humans to be complete idiots. But I do not speak for the airlines, you know your business more than me, you may not need to know how to add or subtract where a one way ticket cost more than a round trip and they sell more tickets than the plane has seats. (just Kidding)
