Частые вопросы
Is it like Casio 580 / 880?
Layout and features follow ClassWiz EX/CW for practice. Independent ClassOn product, not Casio-certified.
Is it free?
Yes. Free in the browser, no account required.
Allowed in exam rooms?
No. Practice only before exams; follow official device rules.
Which model should I choose?
Pick fx-580VN X for the common ClassWiz EX keypad used in many Vietnamese exams, or fx-880BTG if you need Spreadsheet, Math Box and graph practice.
Does it work on phones?
Yes. It runs in modern mobile and desktop browsers. Landscape mode is more comfortable for the keypad.
Can I practise equations and statistics?
Yes. Use EQN/INEQ for polynomials and systems, STAT/DIST for statistics and distributions, plus matrix, vector, complex and Base-N modes.
Free online Casio calculator for exam practice
ClassOn’s Casio simulator helps students rehearse fx-580VN X and fx-880BTG workflows in the browser: COMP, STAT, EQN, matrices, complex numbers and more — free, no install, 10 languages.
Why practise on a Casio ClassWiz simulator?
Many maths and science exams allow scientific calculators. Knowing the keypad matters as much as knowing the formula: SHIFT/ALPHA layers, angle mode (DEG/RAD), S⇔D, Ans and mode menus take time to become automatic.
This page is a free online Casio calculator focused on practice — similar muscle memory to ClassWiz EX/CW — so you can rehearse before you sit with a physical device.
fx-580VN X vs fx-880BTG
Switch models at the top of the page. fx-580VN X follows the ClassWiz EX style used widely in Vietnamese classrooms. fx-880BTG adds ClassWiz CW extras such as Spreadsheet, Math Box and f(x) graphing.
- fx-580VN X — everyday COMP, STAT, EQN, BASE, MAT, CPLX practice
- fx-880BTG — spreadsheet grids, Math Box tools, graph sketching
- Both — OPTN/MENU modes, history recall, multilingual UI
Modes you can train
Use the mode chips or OPTN/MENU to jump between calculator modes. Typical exam drills include trigonometry in DEG, quadratic equations in EQN, one-variable stats in STAT, and matrix arithmetic in MAT.
- COMP — expressions, fractions, logs, roots, Ans/M memory
- STAT / DIST — data lists, regression, Normal/Binomial/Poisson
- EQN / INEQ — polynomials degree 2–4, systems, inequalities
- TABLE, CPLX, BASE-N, MAT, VCT, RATIO, CALC, UNIT, CONST…
Tips for faster exam-day confidence
Always confirm DEG vs RAD for trig. After evaluating, use S⇔D to toggle exact/decimal forms. Store intermediates with Ans or M+. Replay expressions from History instead of retyping.
Pair this simulator with ClassOn exam papers and formulas so calculation practice and content revision happen together.
