About

A scientific calculator that shows answers the way your textbook does. Type 1 ÷ 3 + √8 and get 1/3 + 2√2 instead of 3.1617… sin 60° gives √3/2, (1 + √2)² gives 3 + 2√2, and 1/(1 + √2) is rationalized to −1 + √2. The decimal value is shown right below. FREE, NO ADS - Exact fractions, roots and π, with a textbook-style preview - See how an ambiguous expression like 6÷2(1+2) is read before you press = - 0.1 + 0.2 = 0.3 — no floating-point surprises - Trig, inverse and hyperbolic functions, logs, powers, factorials, combinations; DEG, RAD and GRAD - Engineering notation and SI prefixes, digit and number-format settings, landscape keypad - Unit conversion: 94 units in 13 categories, 30 physical constants - Base conversion (2, 8, 10, 16) and bitwise operations - History of your last 30 calculations BARUNSEM PRO (ONE-TIME PURCHASE, NOT A SUBSCRIPTION) - Graphs with roots, extrema and intersections - Equation solver with exact roots like 1 ± √2, linear systems - Matrices with exact fractional inverses and determinants - Complex numbers in rectangular and polar form - Statistics and regression - 1,000-entry history and color themes PRIVACY No sign-up and no internet use. History stays on this device. No ads or analytics. EXAMS Barunsem is a phone app, so it cannot be used in exam rooms. Bring a calculator your exam allows; use Barunsem for study, practice and work.
