Education
Andrew Borne
Step-by-step math and calculator tutorials make up the core of this library, covering statistics, algebra, geometry, trigonometry, and TI-84 or TI-30XS workflows. The videos favor short, task-led lessons, with several established guides drawing substantial audiences, alongside occasional teaching-technology tutorials. It is most useful for students and educators seeking practical calculator procedures or concise refreshers on specific math concepts. A small number of uploads move beyond the main instructional focus into product reviews and personal-interest videos.

Deep Dive
Andrew Borne: Math Problem Solving with TI Graphing Calculators
Main focus
Andrew Borne pairs high school and college math instruction with hands-on guidance for TI-83+, TI-84+, and TI-Nspire graphing calculators. The focused lessons help learners connect calculator functions to course-related problem solving.
Why it matters
Students working through a calculator-based assignment can quickly find targeted help with the tools used in class. Andrew Borne is especially useful for turning a specific TI function into a practical part of math study rather than treating the device as a separate subject.
Style
Focused walkthroughs place calculator operations alongside math tasks, keeping the emphasis on usable procedures. The compact catalogue favors direct support for particular models and functions over broad, survey-style lessons.
Consistency
Across 89 videos, the archive maintains a clear concentration on math learning and TI graphing-calculator support, making it well suited to focused reference use.
- TI-83+ calculator use
- TI-84+ calculator functions
- TI-Nspire handheld guidance
- High school mathematics
- College-level math support
- Calculator-based problem solving
Check that a tutorial matches your calculator model and operating-system version, and follow the methods, permitted tools, and notation required by your course or instructor.
