How to Use This TI-34 MultiView Calculator Online
I built this page because of something that happened with me. I forgot my calculator when I needed it urgently, so I made a working copy of the TI-34 MultiView key layout and its 4-line screen. That’s the calculator which is asked for in a lot of middle school classes, and it’s used for pre-algebra, algebra and geometry. So if you forget your physical calculator, you can use mine with ease.
This TI-34 MultiView calculator online makes it simple for students. Just tap the keys or type on your keyboard, hit enter and the answer shows up at the bottom. You can see the older and newer sums side by side, which makes it easy to compare the answers, and nothing leaves your browser. There is no install and what you type is not going anywhere.
Why Use a TI-34 Calculator Online?
I made this on purpose because mostly the real one is not always with you. So students use this online TI-34 calculator to finish homework on a laptop and phone, and to rehearse the exact key order before a quiz. Even parents like this calculator. They can sit next to their kids and press the same buttons their kids press in class, even if they have never owned a TI-34 calculator.
Teachers, put it up on the projector. It's a quick way to walk a whole class through fractions, powers or trig on one big TI-34 MultiView calculator. Since it's just a web page, it runs fine on school Chromebooks, tablets and phones.
What Each Key Does
n/d Fractions
Numerator first, then n/d, then the denominator. The fraction shows up stacked like it is shown in your textbook, and results stay exact too, so 2/3+1/4 comes out as 11/12 rather than a long string of decimals.
f◄►d Fraction ↔ Decimal
Once you get your answer, press f◄►d and it will switch between fraction and decimal (3/8 and back again). It works on tidy decimals also, so 0.75 turns into 3/4. Something like √2 can't be a neat fraction, though, so that one stays a decimal.
xⁿ x² √ x⁻¹ Powers and Roots
xⁿ handles any power: 2 xⁿ 5 gives 32. x² squares whatever sits right before it, whether that's a number or a bracket. For √, start the root, type the number, then close it with ) or simply press enter. And x⁻¹? That's the reciprocal. 4 x⁻¹ = 1/4.
(-) Negative Numbers vs - Subtraction
This catches a lot of students out. (-) makes a number negative and - subtracts. Type (-)3 x² and you will get -9, not 9, because the calculator squares first and then applies the minus. The real one behaves the same way as this one.
sin cos tan and mode
Degrees are the default. You'll see DEG in the top-left corner. Press mode once for radians (RAD), and once more to go back.
Editing: ◀ ▶ ▲ ▼ delete clear
Made a mistake? Don’t erase everything. Move the cursor with ◀ ▶ and fix just that bit. delete removes whatever is to the left of the cursor, clear empties the entry line, and pressing clear again clears your history too. With ▲ ▼ you can then pull an old entry back down, change it and run it again.
Using Your Last Answer
Start a new line with +, ×, ÷, xⁿ, x² or x⁻¹ and the calculator slips ans (your last answer) in front for you. The handheld does exactly this. So after 5 enter, typing × 2 enter gives 10.
Keyboard Shortcuts
Here is the list of keyboard shortcuts and what each one does.
| Keyboard key | What it does |
|---|---|
| 0–9 and . | Digits and decimal point |
| + and - | Add and subtract |
| * or x | Multiply (×) |
| / | Divide (÷) |
| ^ | Power (xⁿ) |
| ( and ) | Brackets |
| p | π |
| Enter or = | Calculate |
| Backspace | Delete |
| Esc or Delete | Clear |
| Arrow keys | Click any key first, then move the cursor and scroll history |
Step-by-Step Examples
Try these three on the calculator above. I've listed every key press, plus the answer you should end up with.
Example 1: Adding Fractions with Unlike Denominators
Problem: Calculate 2/3 + 1/4
- Press 2 then n/d then 3
- Press +
- Press 1 then n/d then 4
- Press enter
Example 2: Area of a Circle Using π
Problem: Find the area of a circle with radius r = 6 (A = π × r²)
- Press π
- Press ×
- Press 6 then x²
- Press enter
Example 3: Negative Numbers and Order of Operations
Problem: Calculate (−4)² − 3 × 2
- Press ( (-) 4 ) then x²
- Press - 3 × 2
- Press enter
Error Messages and What They Mean
SYNTAX ERROR
Something's missing, or it's in the wrong spot. Two operators side by side (5 + × 2), an empty fraction and a stray closing bracket are the usual suspects.
DIVIDE BY 0 ERROR
Somewhere in the sum you're dividing by zero. 0 x⁻¹ counts, and so does a fraction with 0 on the bottom.
DOMAIN ERROR
The function can't take that number. Square roots of negatives do this, and so does tan 90° in degree mode.
Press any key to get your entry back. Then use ◀ ▶ and delete to fix it.
TI-34 MultiView vs. Other Scientific Calculators
Most students end up with one of these three. There's a simulator for each on this site, but for the full function list of the real thing, the official guidebook is your best bet.
