You can use the arithmetic operators and any additional functions displayed by the calculator. Available functions may vary by implementation.

Question 2

Does the calculator follow the order of operations?

Accepted Answer

Standard calculators normally apply operator precedence, but use parentheses where supported to make the intended grouping explicit.

Why is a decimal result rounded?

Accepted Answer

Digital calculators use finite numerical precision and may display a limited number of decimal places.

Question 4

Can I use the calculator for financial decisions?

Accepted Answer

It can support arithmetic, but financial decisions may require specific formulas, rates, taxes, fees, dates, and professional advice.
