48/2(9+3)

I don't know that particular calculators, but it makes sense to give precedence to an implicit multiplication operation over a division. To people not seeing this, forget the parentheses and even the numbers, and think of "a/2b": is that "(a/2)b" or "a/(2b)"?

Problem lies in the way the term is written. as soon as like 3rd grade, you write x/y as

x
_
y

OP cut your nails.

nice fingers i like em

Did someone tried to calc this way

48/2*(9+3)=288

48/2/(9+3)=2

Somehow might happen that calc dont show operation before brackets.

Here's a thought: trim your nails. Oh, and teach your calculators order of operations.
