Basic calculator
Add, subtract, multiply and divide — large keys, nothing else in the way.
What do these numbers mean?
- The display shows the current number or the last result. % divides the displayed number by 100 (25 becomes 0.25); ± changes its sign. This calculator applies operations sequentially.
- In decimal numbers, commas separate thousands and a dot separates decimals: 1,234.5 = 1234 + 0.5. ×10^3 means multiply by 1000; ×10^-3 means divide by 1000. Display rounding can make tiny differences between shown totals.
