I-Calculator eyinhloko
I-calculator emahhala, esheshayo esekelwe e-aritmetics yansuku zonke - ukuhlanganisa, ukususa, ukuphindaphinda, ukwahlukanisa kanye nengxenye.
Malunga nale khadi
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.
Imibuzo ebuzwa kaningi
Usebenza kanjani lo mlinganisi?
Ngenisa inani kanye nabasebenzi ngezinkinobho zesikrini noma ibhodi lakho lokushaya. Ibala kusuka ekhohlo kuya kwesokudla njengoba uhamba, njenge-calculator yephoyinti ejwayelekile, futhi ibonisa inani eliphelele elihambayo. Chofoza = ukuze uthole imiphumela ephelile futhi C ukuze uhlanze.
Ingabe ngisebenzisa ibhodi yezitshixo yami?
Yebo. Izinkinobho zenani, + − * / ezisebenza, Enter noma = ukubala, Backspace ukucima, ne Escape ukucima yonke imisebenzi.
Yini isithonjana se%?
Isiqongo sephesenti siguqula inani lamanje libe yiphesenti lenani elihambayo — isibonelo 200 + 10% kunikeza 220 (10% we 200 engeziwe).
Ngiyibala kanjani inketho noma inkokhelo?
Uma ufuna i-15% ye-tip ku-40, chofoza 40 + 15% ukuthola i-46. Uma ufuna i-20% yokulahleka, chofoza 50 − 20% ukuthola i-40. I-key ye-percent iphatha ukungeniswa njengephesenti lenani eliphelele elihambayo.
Kungani 2 + 3 × 4 inikeza 20 kule calculator eyinhloko?
Ngenxa yokuthi ibheka kusuka ekhohlo kuya kwesokudla njengoba isithonjana ngasinye sicindezelwa, ngakho 2 + 3 yenza 5 bese × 4 yenza 20, ngaphezu kokwenza ukuphindaphinda kuqala. Uhlelo oluqinile lwemisebenzi sebenzisa i-calculator yesayensi, echaza ingxenye yokukhuluma yonke ngasikhathi sinye.
Ngizocima kanjani i-calculator noma ngilungisa iphutha?
Chofoza C (noma Escape kwikhibhodi) ukucisha konke bese uqala kabusha, futhi i-Backspace ukucisha inani elidlulele ongenise ngaphandle kokucisha i-sum ephelele.
Yini okuyenza inkinobho yophawu lwe-±?
Ishintsha izimpawu zenombolo esithombeni, ishintsha inani eli positive eli negalelo noma inani eli negative eli negalelo — elifanele ukukhishwa noma ukungeniswa kwenani eli negalelo.
Izibalo ziyisilinganiso esisetshenziswa ukuqondisa kuphela, hhayi ukucebisa ngezimali, ukwelashwa noma ukukhokha.
