Daniel Machado

I am a Mathematics Professor, graduated from the Faculty of Exact, Chemical, and Natural Sciences at the National University of Misiones (UNAM), in Argentina.

This site was born out of a real frustration: seeing high school and college students waste hours trying to understand magical results thrown out by online tools that don't explain the process or give approximate decimals when you need exact answers. We've all been there: solving a study guide before an exam, looking for help online, and finding confusing results or unexplained formulas.

RigelUp emerged to change that, creating a safe and professional space for math students. Each calculator and interactive tool has a single goal: to give you precision, explain the reasoning behind each calculation, and help you level up with confidence.

Other Projects

In addition to this site, I develop other educational projects related to different areas of mathematics.

• Flamath: was the first website I created; it is mainly oriented toward logic, functions, and sets, with an approach designed to lay solid foundations and work on fundamental concepts that appear time and again throughout mathematics.
• Exponty: is dedicated to analytic geometry, with a particular focus on conic sections.
• Dexmath: this project is dedicated to mathematical analysis. Currently, the main focus is on numerical sequences and series.
