About Standard Calculator
This calculator follows normal order of operations, so multiplication and division are worked out before addition and subtraction regardless of the order you typed them in.
Percentage works in context: entering 200 + 10% gives 220, while 200 × 10% gives 20. That matches how people actually use a percentage key.
