Speaking Test vs The Long Division Calculator

App for english test education speach

Solve addition, subtraction, multiplication, and long division step by step. Watch every carry, borrow, partial product, and quotient appear exactly like solving on paper. Arithmetic Calculator teaches arithmetic the way a tutor would — one step at a time, on a real grid-paper canvas. Watch carries propagate, borrows get crossed out, partial products stack up, and long division unfold with an L-bracket, quotient digits, and bring-down arrows. Type any problem and press =. The app generates every algorithmic step, then walks you through each one with a clear explanation. Auto-play mode advances automatically, and optional spoken narration reads each step aloud. FOUR OPERATIONS, FULLY VISUAL • Addition — column-by-column with carry propagation and checkmarks • Subtraction — borrow visualization with cross-out and rewrite in blue • Multiplication — partial products, carry rows, and decimal alignment • Long Division — L-bracket, quotient, products, differences, bring-down arrows, remainders, and repeating decimal detection. Decimal support for all operations. THREE MODES TO LEARN Solve — Free-form calculator with a full keypad. Type any equation using +, −, ×, ÷. Multi-operand problems (3+ numbers), decimals, and negative numbers all supported. Step through the solution at your own pace or let auto-play walk you through it. Practice — Fill-in-the-blank worksheets. A complete problem appears on the grid with blanks in the right places. Fill each blank in algorithmic order — carries, borrows, result digits, partial products, quotient digits. Hints available for every blank. Choose Easy, Medium, or Hard difficulty. Quiz — Test your skills. Pick an operation (or mix all four), choose a difficulty, and answer 5–20 questions. See your score, review wrong answers, and retry instantly. SPOKEN NARRATION Enable Step Audio and the app reads each solving step aloud using your choice of device voices. In auto-play mode, the next step waits until the narration finishes — no rushing ahead. PROGRESS YOU CAN SEE • Daily goal tracker with configurable target • Current streak and best streak counters • Achievement badges for each operation and streak milestones • Per-operation completion counts • Full worksheet history — tap any past session to replay all steps on the grid BUILT FOR HOW YOU WORK • Light, Dark, and System appearance • Haptic feedback on every keypress and interaction • Adaptive layouts for iPhone portrait, iPhone landscape, and iPad • Operations Guide with illustrated examples for all four operations • Configurable division style (Detailed or Conventional) and decimal precision
