"Standard" calculator does not take into account order of operations

[jarmo]

When using "Standard" calculator, then order of operations is not taken into account and calculation value is wrong. For example:

8 + 6 * 2 = 28

Correct answer should be:

8 + 6 * 2 = 20

When using "Scientific" calculator then same calculation is shown in the UI, but calculation is done correctly (e.g. value 20 is shown). If it is intentionally done so that "Standard" is like a "stupid" version of calculator, which performs calculations immediately when entering values, then calculation should be shown as two different operations - first "8 + 6 = 14" and then "14 * 2 = 28".

Steps To Reproduce

1. Open Calculator
2. Enter number "8".
3. Enter "+".
4. Enter "6".
5. Enter "*".
6. Enter "2".
7. Press "Enter" to see the calculation value.
8. Value of "28" is shown, which is mathematically incorrect.

Expected behavior
Should show a calculation value of "20", which is mathematically correct.

Additional context
Same problem applies when pasting in the equation as a whole (e.g. "8+6*2").

Hi Jarmo.

This appears to be a duplicate of #138.

Standard Calculator mode works in immediate-execution mode, just as a simple pocket calculator would. It ignores order of operations entirely. The solution today would be to use Scientific Calculator, though we have discussed this on the team in the past and agree we can do better at making this distinction clearer.

Let me know if you think this issue is different.

Sincerely

Rudy
