The app performs step-by-step calculations with detailed solutions using the correct formulas. You can work with matrices up to 5×5 and vectors in 2D or 3D. Each calculator includes a brief theoretical overview to help you understand the concept behind the operation. It also includes a random number generator to instantly create practice problems with random values. Available in 8 languages: English, French, German, Italian, Portuguese, Spanish, Russian, Ukrainian. Whether you're learning, teaching, or solving real-world problems, Linear Algebra app helps you get accurate results quickly and understand the math behind them. The application perform following operations with matrices: • Matrix addition • Matrix subtraction • Matrix scalar multiplication • Matrix square • Matrix multiplication • Matrix transposition Determinant calculations: • Calculation of the determinant using the Sarrus method • Calculation of the determinant using the Laplace method Vector operations: • Vector Length • Vector coordinates by two points • Vectors addition • Vectors subtraction • Scalar and vector multiplication • Scalar product of vectors • Cross product of vectors • Mixed (scalar) triple product • Angle between two vectors • Projection of a vector onto another vector • Direction cosines • Collinear vectors • Orthogonal vectors • Coplanar vectors • Area of triangle formed by vectors • Area of a parallelogram formed by vectors • Volume of pyramid formed by vectors • Volume of a parallelepiped formed by vectors Download now and simplify your linear algebra work!

Get ready for the LPIC-1 Linux certification with 500 original practice questions you can study anytime, anywhere - completely offline.

All questions are original and based on publicly available information about the exam objectives. WHAT'S INSIDE 500 original questions organized around the ten topic areas of LPIC-1 (exams 101-500 and 102-500): - System Architecture (boot process, kernel modules, runlevels and systemd targets) - Linux Installation and Package Management (partitions, GRUB, dpkg/apt, rpm/yum/dnf) - GNU and Unix Commands (the shell, text streams, filters, regular expressions, processes) - Devices, Linux Filesystems, and the Filesystem Hierarchy Standard (mount, permissions, links, FHS) - Shells and Shell Scripting (environment, variables, conditionals, loops, simple scripts) - User Interfaces and Desktops (X11, display managers, desktop environments, accessibility) - Administrative Tasks (users and groups, cron and at, localization and time zones) - Essential System Services (system time, logging, mail transfer agents, printing with CUPS) - Networking Fundamentals (TCP/IP, addressing, persistent configuration, troubleshooting, DNS) - Security (account and host security, TCP wrappers, SSH and GnuPG encryption concepts) EXAM-STYLE QUESTIONS Questions mirror the style of the real exams - command and option identification, file paths, configuration files, concepts, and short troubleshooting scenarios - so you practice the way you will be tested. MULTIPLE-CHOICE FORMAT Every question uses a clean four-option format. Submit your answer to instantly see the correct choice and a clear explanation, so you learn as you go. REVIEW MODE Missed questions are collected automatically so you can focus on your weak spots and turn them into strengths. BOOKMARKS Save important or tricky questions to revisit later and build your own focused review set. STUDY STATISTICS Track accuracy by topic with simple charts, so you always know what needs more work before exam day. 100% OFFLINE & PRIVATE No account, no login, and no in-app purchases. All content is bundled in the app and all progress is stored locally on your device. Nothing is sent to any server. Buy once and study as much as you like. Good luck on your journey to becoming a Linux professional.
