How to Count Change...

It is mystifying to some of us in the world as we watch people who don't know how to count change without a calculator or a pen and paper. Just this week, I watched at a big box store as two cashiers try to figure out how much change to give a man. They had to get out a pen and paper.
I realized several years ago that the problem is some people think that it is a subtraction problem. When they take out the paper, they write down how much cash they were given and then subtract the total cost of the purchase.
When in reality it is so much simpler than that.
What they haven't been taught it is really an addition problem, you simply count UP from the total cost, to the amount of the cash tendered.

That's it.
So for those of us who know, be patient because now you know the reason why. Be patient or teach others how to solve this baffling math problem.

What I do here is simply share our preparedness journey. If you liked this post we would love it if you joined our Perky Prepping Gramma community on Facebook, comment or share. Plus it would just make my day.
