Covers basic arithmetic, algebra, fractions, scientific calculations, and matrices
Fully in Spanish — interface, explanations, and step breakdowns
Works on any device — mobile, tablet, and desktop
Completely free with no login or account required
No ads, no paywalls, no distractions
A high school student solving quadratic equations and needing to see the full working process
A university student checking their algebra or matrix calculations step by step

A parent helping their child with homework and verifying each step is correct
Anyone learning math independently who wants to understand the logic behind every answer

Here's your Makers Comment for Fazier: I built Calculadora Alicia because I kept running into the same problem — Spanish-speaking students have almost no tools that actually explain math to them. Every calculator online gives you the answer. But students don't just need the answer. They need to understand why that's the answer and how you get there. That gap is what Calculadora Alicia fills. The idea was simple: build a calculator that thinks like a teacher, not a machine. One that shows every step of the solution in plain Spanish so the student walks away actually understanding the process — not just copying a number. What surprised me most during the build was how much the step-by-step explanation changed the way people used it. Once users could see the working, they started using it to learn, not just to check answers. That shift validated the whole concept. Right now it covers basic arithmetic, algebra, fractions, scientific calculations, and matrices. All free. No account. No install. Just open and solve. If you're a student, a teacher, or someone who's always wanted to understand math better — give it a try. Honest feedback from this community means a lot at this stage.
