Frequently Asked Questions

What modes does the Scientific Calculator support?

The calculator supports five modes. Basic handles standard arithmetic with full order-of-operations support. Advanced unlocks trigonometric functions (sin, cos, tan and their inverses), logarithms (log, ln), exponentials, and roots. Calculus mode supports symbolic and numerical derivatives, definite and indefinite integrals, and limits. Complex mode handles imaginary numbers and complex arithmetic. Statistics mode provides mean, median, mode, standard deviation, variance, and regression analysis.

Can I use different angle modes for trigonometric functions?

Yes. The calculator supports Degrees (DEG), Radians (RAD), and Gradians (GRAD). Switch using the angle mode selector at the top of the calculator. Degrees are standard for everyday geometry — a right angle is 90°. Radians are preferred in calculus and higher mathematics — a full circle is 2π radians. Gradians divide a right angle into 100 parts and are used in surveying. The mode affects sin, cos, tan, and all inverse trig functions.

How do I enter complex expressions?

You can type directly into the input field or use the on-screen buttons. The calculator supports parentheses for grouping: (2+3)*4 gives 20. Functions require parentheses around the argument: sin(45), sqrt(16), log(100). Constants pi and e are available as buttons or can be typed. You can chain operations freely: "2 * sin(pi/4) + sqrt(16)" computes to 5.414. Syntax highlighting shows functions, operators, and constants in different colors to help spot errors.

What is dual calculator mode?

Dual calculator mode opens two fully independent calculator panels side by side. Each panel has its own expression, history, angle mode, and numeral system settings. This is useful when you want to compare two different approaches to the same problem, convert a result between numeral systems, or keep a reference calculation visible while working on a new one. You can link the two calculators to share settings, or keep them fully independent.

Does the calculator support different numeral systems?

Yes. You can display and input numbers using Western Arabic (0–9), Hindi/Devanagari (०–९), Eastern Arabic, Bengali, Burmese, Thai, and several other numeral scripts. The numeral system selector is available in settings. All calculations are performed in standard floating-point arithmetic regardless of display script, so accuracy is unaffected.

Can I save my calculation history?

Yes. Every calculation is automatically logged in the history panel on the right side (or accessible via the History button on mobile). Each entry shows the expression and result. You can click any history entry to restore that expression to the input field. You can also add a text note to any history entry for reference. History is stored in your browser's local storage, so it persists across sessions on the same device without any account or sign-in required.

What calculus operations are supported?

Calculus mode supports derivatives, integrals, and limits. For derivatives, use derivative(expression, variable) — for example, derivative(x^3 + 2*x, x) returns 3*x^2 + 2. For definite integrals, use integral(expression, variable, lower, upper) — for example, integral(sin(x), x, 0, pi) returns 2. Indefinite integrals return the antiderivative as a symbolic expression. Limits use limit(expression, variable, value).

How do I enter scientific notation on this calculator?

To enter a number in scientific notation, use the "E" notation: type 3.5E6 for 3.5 × 10⁶, or 2.1E-4 for 0.00021. You can also use the EXP button on the Advanced mode keypad. The calculator displays results in scientific notation automatically when numbers are very large or very small.

Can I use this as a free Casio calculator online?

Yes — Solmint's scientific calculator supports the same core functionality as a Casio fx series calculator, including natural display of fractions and expressions, all standard trig and log functions, a multi-line input field, and memory storage (M+, M−, MR, MC). It also goes further with calculus mode (derivatives and integrals), complex number support, and calculation history with notes.

Does this scientific calculator work on mobile without downloading anything?

Yes. The calculator runs entirely in your browser on any device — phone, tablet, or desktop — with no app download, no installation, and no account required. The mobile layout is fully optimized with a responsive keypad, scrollable history panel, and touch-friendly buttons.

Can I use this scientific calculator for SAT or ACT exam prep?

Yes. The Advanced mode covers all functions tested on the SAT and ACT: trigonometry (sin, cos, tan), logarithms, exponentials, square roots, and statistical functions. While physical calculators are required in the actual exam, this tool is ideal for homework, practice problems, and understanding concepts before test day.
