With only a little practice, I found I can add up a column of 4-digit numbers in seconds. Faster than you can whip out your calculator app.
Its the impression that computers are easier, that gets me. Why not practice for 2 minutes and learn a better way? Instead of limping along with the computer all your life.
Its not a point of pride, you know, to remain unskilled in the ordinary things of life. It takes only a few minutes to learn these things. I wonder why anyone would resist?
