How to use the tool
- Start untimed and write a clean setup before calculating.
- After an error, identify whether it came from setup, arithmetic, or units.
- Repeat the same level until accuracy is stable, then switch to timed mode.
- Apply the skill in a business drill or full case.
What difficulty means
Beginner questions train multiplication, intermediate questions train common percentages, and advanced questions train exact division. These levels describe the arithmetic in this tool; they are not predictions of interview performance.
