CalcEmu

This page is a free online emulator of the TI-30XS MultiView scientific calculator. Every key is where it is on the real device: 2nd, mode, n/d for stacked fractions, x10ⁿ, table, data, the trig keys, log and ln, powers, parentheses, the answer toggle and enter. Results show as fractions, exact square roots or multiples of pi, and one key switches them to decimals. The calculation engine does exact rational arithmetic, so 2/3 + 1/6 is 5/6, not 0.8333. It runs entirely in your browser, with no account, no download and nothing sent to a server.

How to use

  1. Click the keys or type on your keyboard: digits, + - * / ^ ( ), Enter to calculate, Backspace to delete, Esc to clear.
  2. For a fraction press n/d, type the numerator, press the down arrow, type the denominator, then the right arrow to leave the fraction.
  3. Press the ◄► key under + to switch the last answer between fraction and decimal, or between exact pi or root form and decimal.
  4. Press mode and choose DEG, RAD or GRAD before trigonometry; press 2nd then quit to return to the home screen.
  5. Press table, enter a function of x, set Start and Step, and read off the values; press data to enter lists and 2nd stat for 1-Var or 2-Var statistics.

FAQ

Is this the official TI-30XS MultiView software?

No. It is an independent emulator that imitates the key layout and behaviour of the TI-30XS MultiView so you can practise. It is not made by or affiliated with Texas Instruments.

Can I use it in an exam?

No. Exams that allow the TI-30XS expect the physical calculator you bring, and the GED test provides its own on-screen version inside the testing software. Use this page to practise the keys so the real one feels familiar.

Why does 2 ÷ 3 give 0.6666666667 but the n/d key gives 2/3?

That is how the real calculator behaves. The ÷ key gives a decimal answer and the n/d key keeps a fraction. The ◄► toggle key converts either answer to the other form.

Does it work on a phone?

Yes. The keypad fits a 375-pixel-wide screen with every key at least 40 pixels tall, and it works with touch.

Is anything stored or sent anywhere?

No. Everything runs in your browser. Closing the page clears the history, the stored variables and the data lists.
