If we look at this expression $\frac{A}{B + C}$ It looks like it is simply $A ÷ B + C$
But the calculator does it as $A ÷ ( B + C )$
Why does the calculator do it like this as in the first place there are no brackets.
I have attached calculator result screenshot.
On many calculators nowadays, when you press the ÷ button or the fraction "-" button, you automatically stay in the divided part until you choose to come out of it. So if you want to do $A ÷ B + C,$ you have to press on your calculator:
$A$
÷
$B$
$>\quad $ (Right Arrow (to come out of the divided part)
$+$
$C$.
Why this is the case? I do not know. But it's not a big deal, right? Just get used to it.
