Quick Start

Four steps to get a result on the simulator, the same workflow you use on a Casio fx-series scientific calculator.

1
Type or tap your expression
Enter numbers and operators with the on-screen keypad or your physical keyboard. The slash key inserts a fraction divider, the caret key inserts an exponent.
2
Pick degrees or radians
Tap the Deg / Rad button on the device to set the angle mode for trigonometry. The active mode is shown on the LCD header so you can confirm before pressing equals.
3
Use Shift for second functions
Tap Shift to expose inverse trigonometry, cube root, nPr, and nCr. The amber labels above each key show the second function while Shift is active.
4
Press equals to compute
Press the amber equals key (or Enter on your keyboard) to evaluate. The result appears on the answer line and is stored as Ans for the next expression.

Popular Modes

The simulator opens in Basic mode by default. The mode tabs above the keypad expand the simulator into specialised workflows for matrices, complex numbers, statistics, and equation solving.

Matrix mode

Add and multiply 2x2 and 3x3 matrices, find determinants, and invert square matrices in a guided panel.

Determinant
Multiplication
Inverse

Complex mode

Add, subtract, multiply, and divide complex numbers in rectangular form. Convert to polar form to find magnitude and angle.

Rectangular

Magnitude

Statistics mode

Enter a single-variable data set to find mean, sample and population standard deviation, variance, and quartiles in one tap.

Std deviation
Quartiles

Equation solver

Solve linear systems with two and three unknowns, and quadratic and cubic equations with real coefficients.

Review and Methodology

Updated May 8, 2026

This calculator runs locally in your browser. Inputs are converted into the units required by the formula, and the result is paired with supporting references so you can verify the method before using it for planning or estimates.

Worked Example

1Step 1: Press sin, then enter 30, then close paren

2Step 2: Confirm Deg mode is shown on the screen

3Step 3: Press equals

Result: 0.5

The same input in Rad mode returns about -0.988, because 30 radians is roughly 4.77 full turns.

About this Casio-style scientific calculator simulator

This simulator recreates the workflow of a classic two-line scientific calculator. The input line on top shows what you have typed, and the result line below shows the answer once you press equals. The keypad is laid out in the same general groups as a Casio fx-series device, so muscle memory transfers if you switch between this simulator and a physical calculator on exam day.

Two-line display so you can verify the expression before pressing equals
Shift modifier exposes inverse trigonometry, cube root, nPr, and nCr without a separate menu
Deg and Rad toggle for trigonometric functions, with the active mode shown on the screen header
Full keyboard input, plus a tap-friendly mobile keypad and a fullscreen mode for small screens
Calculation history that you can click to re-load any previous expression

It is an independent educational tool. It is not affiliated with, endorsed by, or sponsored by Casio. Use it for revision and homework, then sit your exam with the physical calculator your exam board approves.

You can also calculate changes using our Scientific Calculator, Fraction Calculator or Percentage Calculator.

Frequently Asked Questions

Is this an official Casio calculator?

No. This is an independent educational simulator built by Calculory. It is not affiliated with, endorsed by, or sponsored by Casio. The simulator recreates a familiar two-line scientific calculator layout for practice and revision.

Can I use this calculator simulator in an exam?

Most exam boards require an approved physical calculator and ban any internet-connected device during a test. Use this simulator for homework, lecture practice, and revision, then bring your approved physical model on exam day.

Does the simulator support fractions?

Yes. In Basic mode, type the numerator, press the a/b key (or the slash key on your keyboard), then type the denominator. The result is shown on the answer line. Fraction mode adds a focused two-input panel that returns the simplified fraction and its decimal value.

How do I switch between degrees and radians?

Tap the Deg/Rad button at the top of the calculator. The active mode is shown on the screen header so you can confirm before pressing equals. Trigonometric functions like sin, cos, and tan are interpreted in the selected mode.

How do I use the Shift key?

Tap Shift to expose the second function on each key, shown in small text above the main label. Common Shift functions include inverse trigonometry (sin to sin inverse), cube root (sqrt to cbrt), nPr, and nCr. Pressing Shift again or selecting any key cancels the Shift state.

Does the simulator support matrices, complex numbers, and statistics?

Matrix, Complex, and Statistics modes are available as tabs and will be expanded in upcoming releases. For now, use Basic mode for most calculations and Calculory has dedicated tools for matrix operations, complex number arithmetic, and statistical summaries.

Can I drive the simulator with my keyboard?

Yes. After clicking once on the simulator, your keyboard digits, operators, and Enter (equals), Backspace (delete), and Escape (clear) all work. The slash key inserts a fraction divider, and the caret key inserts an exponent.

Is the simulator free?

Yes. Calculory simulators are free, run in your browser, and do not require sign up. There are no usage limits and no ads on the calculator screen itself.

Is it possible to embed the Casio-Style Scientific Calculator on another website?

Yes, embedding the Casio-Style Scientific Calculator is free. Hit the "Embed" button on this page, adjust the width, height, and theme, then grab the iframe code. It works on WordPress, Wix, Squarespace, Shopify, and plain HTML pages. No registration needed. Full instructions at calculory.com/services/embed-calculators.
