Math Practice vs Mental Math

The clean, distraction-free app for drilling math — from basic arithmetic to powers and roots. Whether you're a student building fluency or an adult keeping your mental math sharp, Math Practice gives you focused, repeatable practice with instant feedback. ARITHMETIC MODE Practice addition, subtraction, multiplication, and division. Problems are shown in vertical and horizontal formats just like on paper, so you build real problem-solving habits — not just screen tapping. Choose your difficulty: · 1-digit × 1-digit · 2-digit × 1-digit · 2-digit × 2-digit For two-digit multiplication, the app walks you through each step separately — breaking the problem into partial products so you understand the method, not just the answer. ADVANCED MODE Ready for more? Switch to powers and roots: · Squares (x²) and Cubes (x³) · Square Roots (√) and Cube Roots (∛) Adjust number size from single-digit to three-digit ranges to match your level. HOW IT WORKS Type your answer one digit at a time — each digit has its own box. The app checks instantly: a green flash and a sound means you got it right. A shake and a direction hint means try again. No multiple choice. No guessing. Real answers only. FEATURES · Two practice modes: Arithmetic and Advanced · Adjustable difficulty for every operation · Step-by-step guidance for long multiplication · Direction hints when your answer is off · Sound and animation feedback · Tracks your correct answers over time · Works offline — no internet needed
