The basic calculator is the everyday, no-frills tool for quick arithmetic. Tap the buttons or use your keyboard to add, subtract, multiply and divide, work out percentages, or flip a number’s sign — it works instantly on any device with no sign-up. This is the plain four-function calculator most people reach for day to day. For trigonometry, logarithms, powers and roots, use the scientific calculator; for a mortgage or budget, see the finance calculators instead.
It behaves like a classic pocket calculator: you enter a number, choose an operator, enter the next number, and it evaluates left to right as you go, showing a running total on the display. The equals key finishes the current calculation, the percent key turns the current entry into a percentage of that running total, the sign key flips positive to negative, and the clear key resets everything. Everything responds to the keyboard too, so you can type as fast as you think.
For a worked example, keying 200 + 10 % gives 220, because the percent key reads 10 % as 10% of 200 (that is 20) and adds it on; keying 50 × 3 − 20 = returns 130. Reach for it to split a bill, add up a shopping list, work out a discount or tip, or do any of the quick sums that come up through the day without opening a spreadsheet.

Imakhala yowerengera kuchokera kumanzere kupita kumanzere monga momwe mungathere, monga momwe mungawerengere pa pulasitiki, ndipo imasonyeza kuchuluka kwa ntchito. Dinani = kuti mupange zotsatira za kumapeto ndi C kuti muchotsa.
Kodi ndingagwiritse ntchito ma keyboard anga?
Yes. The idadi zigawo, + - * / kwa ogwira ntchito, Enter kapena = kuti kafukufuku, Backspace kuchotsa, ndi Escape kuchotsa zonse ntchito.
Kodi % key ndi chiyani?
The peresenti batani amasintha mnda watsopano kuti peresenti ya kuyendetsa zonse - kwachitsanzo 200 + 10% amapereka 220 (10% ya 200 anawonjezera pa).
Kodi ndingatani kuti ndiwerengere chithandizo kapena kuchepetsa mtengo?
