Quick Answer
Use distributive breakdowns, near-base shortcuts, and factor splitting to reduce multi-step multiplication time.
Why It Matters in Interviews
- Multiplication speed often determines overall case-math pace.
- Pattern recognition lowers cognitive load during pressure.
- Reliable shortcuts reduce careless carrying errors.
Practice Drill Plan
- Train near-base numbers (49x, 51x, 99x) in rapid sets.
- Alternate distributive and rounding methods for the same problems.
- Close with a timed mixed multiplication challenge.
Common Mistakes
- Using one method for every number shape.
- Over-rounding without adjusting back.
- Not practicing under time pressure.
