TI-36X Pro Style Calculator Widget for Your Website

For FE exam review courses, engineering tutors and study blogs: a TI-36X Pro style keypad your readers can press in the same order as the handheld, with a TI-30XS MultiView layout one tap away.

What your readers can do with it

Engineering students preparing for the FE exam learn one calculator and then use it under time pressure, so the key order matters more than the maths. This widget is the TI-36X Pro style calculator from WideMath: the same rows of keys, the green 2nd labels above them and a MathPrint display that stacks fractions and roots.

Where it fits

Put it next to a worked FE problem and write the key sequence under the question. Readers press along, compare their display with yours, and find the step where their own handheld would have gone wrong. It works the same way on a GED maths practice page with the TI-30XS layout selected.

Suggested size

The default frame is 1,000 px high and up to 480 px wide. The calculator sizes itself to the frame, and that height shows the display and every key at any width from a 320 px phone column up to 480 px. At the full 480 px width it fits in about 920 px if you need a shorter frame. Keep the width at 480 px or less on a wide page, so the keys stay the size of a real calculator. On a phone the frame shrinks to the screen width and the keys stay large enough to tap.

A problem that replays its own keys

The widget starts blank, like a handheld after a reset. The keys parameter presses a list of keys, separated by commas, on that fresh calculator. This link solves 2x² − 3x − 5 = 0 with poly-solv:

Open it in a new tab

The widget opens on the solver screen with x1 = 5/2 and x2 = −1. Readers can then press 2nd quit and try the next question themselves. For a GED page, ?model=30xs on its own opens the TI-30XS MultiView layout.

Add it in three steps

  1. Copy the code above, after loading a problem if you want one.
  2. Paste it into an HTML block on the lesson page: Custom HTML in WordPress, a Code block in Squarespace, or the HTML editor in Canvas.
  3. Write the key sequence beside the widget in words, such as "2nd [poly-solv], enter, then the three coefficients", so readers can follow along.

Frequently asked questions

Is this a real TI-36X Pro?

No. It is an independent TI-36X Pro style practice tool built by WideMath, not made or endorsed by Texas Instruments. In the FE exam candidates use an approved handheld; this widget is for learning which keys to press.

Can it show the TI-30XS MultiView layout instead?

Yes. Readers can tap the TI-30XS switch at the top of the calculator, or you can add model=30xs to the address in the code so the widget opens on that layout.

How do I write my own key sequence link?

List the keys after keys=, separated by commas, as in keys=2nd,sq,8,enter for the square root of 8. The easiest way is to press the keys on the full calculator page and use its Share icon, then swap widemath.com/ for widemath.com/embed/ in the address.

Why does the widget open with an empty screen?

It starts the way a handheld does after a reset, so readers practise from a clean state. To open it on a worked answer instead, put a keys= sequence in the address inside the code.
