MathThought Scientific Calculator
An Education That Counts®
The MathThought Scientific Calculator is a free student tool built to support learning across Calculus, Trigonometry, Linear Algebra, and Number Theory. It features a full scientific calculator with hyperbolic functions, matrix computations including eigenvalues, RREF, LU/LDU, null space, column space, and singular value decomposition, a calculation history, and TI-84 style summation and numerical integration tools.
Built by Dr. James Burk as part of the Math Thought Program, a platform dedicated to helping students genuinely understand mathematics, not just memorize procedures.
