I believe the OP's exercise was to do the division manually not mentally.
Basic mental arithmetic is probably the most used in day-to-day life. It feels weird having to whip out a calculator/phone every time you need to make a quick estimate.
- morgante 10y ago> I believe the OP's exercise was to do the division manually not mentally. That's equally useless. Why would I try to figure out the result manually when I have a computer in my pocket at all times? If anything, doing things manually when we have computers seems weirder.
- JoeAltmaier 10y agoWith 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.
- morgante 10y agoGood for you. Do whatever you want. I have a phone with me at all times. It's hardly an inconvenience to use it.
- JoeAltmaier 10y agoIts 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?
- rohit89 10y agoThe point of that exercise was to show whether you knew how to do it. Things like division and multiplication etc are so basic that you should know how to do it even if you haven't done it for years. As for mental arithmetic, its main advantage is speed. Faster to mentally solve and continue along your train of thought/flow of conversation than to pull out a calculator. Physical actions will never be faster than speed of thought.
