About TI34Calc

Who We Are

TI34Calc is run by Ashish Yadav, a digital marketing expert who builds and manages educational websites. Ashish started TI34Calc to give students, parents and teachers a free, easy way to practise scientific calculator keystrokes online, without needing to buy, borrow or install anything.

Ashish's background is in digital marketing rather than classroom teaching, so accuracy is treated as a strict process rather than assumed: every calculator function and worked example on the site is tested in our simulators and checked against standard textbook methods before it is published. When readers report a mistake, it is corrected as quickly as possible.

You can reach Ashish directly at info@ti34calculator.com, the official email address for TI34Calc.

Why This Site Exists

Many middle school and high school classes ask students to use a specific scientific calculator, most often the TI-34 MultiView, TI-30XS MultiView or Casio fx-300ES. Students don't always have one with them: it's left at school, the batteries are flat, or they're doing homework on a phone. Parents helping with homework often don't own the same model at all.

TI34Calc gives everyone a free way to practise the same kinds of keystrokes in a web browser, and explains how to use them for everyday math topics like fractions, exponents, trigonometry and remainders.

What We Offer

We offer three calculator simulators: a TI-34 MultiView style calculator, a TI-30XS MultiView style calculator and an fx-300ES style calculator. They support exact fractions, powers and roots, trigonometry in degrees and radians, and a 4-line display with editable history.

We also publish step-by-step math guides that explain keystrokes, worked examples and common mistakes. Everything on the site is free and needs no account or download.

Who It's For

Students in grades 5–12 who want to practise or check their work, teachers who want to show keystrokes on a projector or whiteboard, and parents who are helping with homework.

How We Check Accuracy

Every worked example on this site is tested in our simulators before it's published, and our calculators use exact fraction arithmetic so answers like 2/3 + 1/4 = 11/12 aren't affected by rounding. If you spot a mistake in a calculation or a guide, please tell us and we'll fix it.

Independence
