This is a very trivial issue. But I am very curious to find out the answer.
Lately, I bought a desk calculator. The way this calculator works is absolutely new and weird to me (and I have used calculator for more than 40 years already).
Let's say you need to do 2+3-4, all in my life with the calculators that I have used before, I would key in [2] [+] [3] [-] [4] [=] and that would give me the correct result of '1'. But with this calculator, keying in that way would give an incorrect result of '3'. In order to get the correct result of '1', I will need to key in [2] [+] [3] [+] [4] [-] [*].
And I still fail to figure out how to use it to do multiplcation or division as I keep getting incorrect results. What kind of calculator is this? I will need to buy another calculator but how can I make sure the calculator that I buy will work in the conventional way, instead of in a wierd way like this one?
