Mathematics Educator & Lead Author · Austin, Texas, USA

Daniel Carter is a mathematics educator based in Austin, Texas, and the lead author at Scientific Calculator Pro, a free online scientific calculator and math-guide website for students, teachers, and anyone who wants a reliable way to check their work.

Over the past 12 years, Daniel has taught Algebra, Geometry, Algebra II, and Precalculus. In the classroom, he saw the same problem again and again: students understood the math but lost marks because of a calculator step — a misplaced parenthesis, the wrong angle mode, or an order-of-operations mistake. His guides are written to fix exactly those problems.

At Scientific Calculator Pro, Daniel writes and reviews the site’s how-to guides. Each guide explains one task at a time, shows the exact calculator steps, works through real examples, and points out the common mistakes students make. His goal is simple: math that feels doable, explained in plain language, with no step skipped.

Daniel holds a Bachelor of Science in Mathematics from the University of Texas at Austin and a Master of Education in Mathematics Education. When he is not teaching or writing, he helps local students prepare for state math assessments and college placement tests.
