Maybe we should eliminate teaching math because our smart phones can do the work for us if needed.
I posted this on the current events board about a week ago, I think it works on this thread.
I went to the movies with my wife and my tickets cost $20.50....I gave the college age girl a $20 and a $5 bill......she gave me 50 cents change, obviously mistakenly thinking I had given her a $1 bill.....
I pointed out that I had given her a $5 and she owed me 4 dollars more....she knew she had made the mistake because the two bills were
on the counter, not in the till yet.
the thing is, she had to use her smart phone to figure out how much more to give me, not trusting I was telling her the correct amount.....
she could not figure the difference between $21 and $25 dollars in change....
hopefully she could have done the math if she really had to, but she did not even try, why bother when the smart phone can do it .....
we all know stories about when you go into a store and give a bill and also some loose change in order to get a bigger bill as change, and they cannot figure it out.....I think my example takes it to a new level
