About Calc84: Democratizing Advanced Math Education
The Problem: Financial Barriers to STEM
For decades, advanced mathematics education has been gated behind expensive hardware. Physical graphing calculators often cost between $100–150 — a prohibitive expense for many students, schools in underfunded districts, and learners in developing countries. This creates an equity gap where access to tools determines access to learning, not ability or curiosity.
The Calc84 project was started in 2026 by indie developer Miqdad Qaisrani to eliminate that barrier. The mission is straightforward: build professional‑grade mathematics tools that run universally in web browsers, completely free. No subscriptions. No paywalls. No hardware requirements. Just pure, accessible mathematics.
The Founder's Story
Miqdad Qaisrani is a full‑stack engineer and cybersecurity student who builds educational software. While studying, he watched classmates struggle with the cost of mandatory graphing calculators — a problem that struck him as both unfair and unnecessary in the age of web browsers. He decided to build a solution that would put a fully functional TI‑84‑style calculator into every student’s pocket, for free.
Calc84 began as a passion project in 2026 and launched publicly the same year. It continues to grow into a complete mathematics suite, and every feature is designed with the classroom in mind — from the TI‑BASIC programming environment to the 2D graphing engine and its 3D slice viewer.
Technical Philosophy: Local‑First Architecture
Calc84 runs all mathematical computations locally in your browser using WebAssembly and optimized JavaScript. Whether you’re graphing parametric equations, computing matrix determinants, or executing TI‑BASIC programs, the processing happens instantly on your device — your calculations never leave your computer. The site also uses third‑party analytics (Google Analytics) and advertising partners (Google AdSense) whose cookies are described in our Privacy Policy; none of them have access to the math you type in.
This local‑first approach keeps your work private, and also means zero latency, offline capability via the PWA, and no server cost for heavy computation — helping keep the tool free.
The Calc84 Ecosystem
Calc84 has grown into a full mathematics suite covering high school and college coursework:
- Graphing Engine: 2D function and parametric plotting compatible with TI‑84 conventions, plus a 3D slice viewer for multivariable functions.
- Matrix Laboratory: RREF, eigenvalues, matrix inversion, and transformation visualization.
- Statistics Suite: Probability distributions, regression analysis, and summary statistics.
- TI‑BASIC Editor: Faithful programming environment for algorithmic learning.
- Unit Converter: AI‑powered conversion for science and engineering.
- AI Math Solver: Step‑by‑step explanations to help you learn.
Our Values & Commitment
Accessibility: Every student deserves high‑quality math tools, regardless of economic background.
Transparency: Calc84 is built with privacy-first principles — no account is required, and your calculator input is never sent to our servers. Aggregate analytics and ad cookies are disclosed in the Privacy Policy.
Privacy by Design: We do not require accounts, we do not sell your data, and we never use your calculations for any purpose other than your own learning.
Continuous Improvement: Calc84 is actively developed (current version v10.6.5) with regular updates driven by educator and student feedback.
Looking Ahead
Future work focuses on classroom collaboration features, expanded language support, and deeper integration with educational platforms — while keeping the local‑first, no‑account architecture. If you’re a teacher, student, or developer who believes math education should be free, we’d love to hear from you.

Frequently asked questions about Calc84
Who created Calc84?
Calc84 was created by Miqdad Qaisrani, a cybersecurity student and independent developer. He started the project in 2026 to lower the cost barrier that expensive graphing calculators place on students.
Is Calc84 really free? Will there be ads?
Yes, Calc84 is free to use for students and teachers, and the core mathematical tools are intended to stay free. We display non‑intrusive ads (through Google AdSense) to cover development and hosting costs. Ads never change how the calculator works, and advertising cookies have no access to the math you type in — see our Privacy Policy.
Why was Calc84 created?
It was created to bridge the equity gap in STEM education. Traditional graphing calculators cost $100‑$150, locking out many students. Calc84 delivers the same functionality in a web browser for free, so every student can learn without financial obstacles.
How does Calc84 protect my privacy?
All mathematical computations run locally on your device using JavaScript and WebAssembly. Your equations, results, and assignments are never sent to any server. The site does use aggregate analytics (Google Analytics) and third‑party ad cookies (Google AdSense) to understand usage and keep the tool free, but those have no access to your math.
