BizMath trains the mental math skills that consulting and finance interviewers actually test. Most math apps drill times tables. BizMath generates over 19 million unique questions, from fast arithmetic scaled to business numbers to full word problems covering revenue & profit calculations, break-even analysis, percentage change, and market sizing. The exact math you'll do on the job and in the interview. QUICK CALCS Fast-paced arithmetic across six operations: multiplication, division, addition, subtraction, percentages, and exponents. Four difficulty levels from Easy to Expert, with numbers scaled to what you'll actually encounter in business contexts. Not textbook problems. WORD PROBLEMS 300 original business scenario templates across four categories: Revenue & Profit, Percentage Change, Break-Even, and Market Sizing. Every scenario uses realistic company contexts and interview-appropriate numbers. BUILT FOR INTERVIEW CONDITIONS • Estimation Mode: Practice the approximation skills interviewers actually reward. Set your tolerance and train yourself to get close fast rather than exact slow. • Timed Practice: Add time pressure to simulate real interview conditions. • Expert Difficulty: Large numbers, multi-step calculations, and trailing zeros. The problems that separate prepared candidates from everyone else. TRACK YOUR PROGRESS Detailed performance tracking across every operation, category, and difficulty level. See where you're strong and where you need work. LEARN Built-in reference guides covering mental math shortcuts, word problem formulas, and the business concepts behind every question type.
