Yes, I figured that out in a few seconds.
Your mother was very bright. I wonder how many of us now could have survived back then.
It seems out of control doesn't it?
It simply astounds me how often I've run into a person who has trouble making simple change ... you can see the wheels grinding as they are trying to come up with something like 72 cents ... my first job was working in a lumberyard ... we had to write up all the orders by hand ... multiple pieces of lumber at a certain price, the tickets often got into the hundreds or even thousands of dollars ... anyway I would do everything in my head ... I had a knack of doing math like that ... it was faster than using a calculator ... I did that one time for a customer, it was for several hundred dollars, he refused to pay saying I added the ticket wrong and complained to my manager ... my manager took the ticket and a calculator and handed them to the customer and told him to add up everything else for himself saying if there was a mistake he could have a 10% discount ... I was nervous but confident I was right ... five minutes later after the guy was finished adding everything up with the calculator the final price was right down to the penny ... the customer mumbled something about still should used a calculator and I said those things slow me down, and went out ot help him load the supplies he just bought
There's a reason why they work at retail
That's insulting to say the least.
It's the truth
I not need calculator, I calcaulate that at my head quickly.
