"I signed up for mbamath.com hoping that I could identify my weaknesses and find a few key takeaways from the web-based lessons. I started immediately and was pleased with the experience. The lessons were easy to understand, well organized, and very relevant.

Having just recently completed my first semester of B-school I can say that mbamath.com was an excellent preparation tool and an outstanding value. If you’re looking for an edge you won’t find a more efficient option."

How Does MBA Math Get You MBA-Ready?

Here are the main incredients of the MBA Math approach:

Strike a Balance Between "Too Little" and "Too Much"

The biggest challenge in designing and delivering the MBA Math course is to include the right topics at the appropriate level of detail. Too little and you get a false sense of security. Too much and you get bogged down, faced with the online equivalent of a bulging 1000-page textbook.

The MBA Math "Just Enough" Active Problem-Solving Approach

The MBA Math course, refined over more than ten years of teaching a 35-hour math camp to incoming first-year MBA students the week before Orientation, strikes that balance.
  • Exercise Driven: You encounter a range of exercises drawn from first-year MBA quantitative courses.
  • Minimal Theory: You review problem-solving approaches and techniques with a minimum of theory.
  • Solve Problems: You spend most of your time solving problems. Not reading. Not listening passively. Wrestling with problems. Building spreadsheets. Computing answers. Actively.

Focus on Getting it Right Eventually Rather than Getting it Right the First Time

The MBA Math course covers 24 modular topics, each with its own quizzes and learning materials.
  • Pre-Quiz: You start with a pre-quiz on a particular topic to establish your starting point. For some topics, your pre-quiz score may well be a big fat zero! There is no reason that you would know about regression, for example, until you have studied it.
  • Study: Guided by your pre-quiz score, you then work through the teaching material and exercises until you understand how to solve problems accurately.
  • Post-Quiz: You take a post-quiz when you are ready. If you are not satisfied with your post-quiz score, you can continue your studying and then take another post-quiz. As many times as you need to attain the proficiency you desire.

Excel Spreadsheets

Basic Excel worksheet techniques are covered in one topic. Additional topic-specific techniques are used in lessons covering the MBA topics below. Solutions illustrate basic functions implementing algebraic formulas and also the built-in functions (e.g., FV, NPV, VAR, STDEV, CORREL, RSQ, NORMDIST) that you will use most often in your MBA experience.

Financial Math

Familiarity with time value of money concepts, formulas, and spreadsheet solution techniques should be considered a prerequisite for your MBA experience. Because everything else in financial math is built on this foundation of shifting one cash payment at one time to its equivalent at another time, you should be clear about this before you start.

Annuities and perpetuities are the simplest smooth patterns of cash flows over time.

Bonds are a mixture of annuities and future values.

Net present value allows you to convert an irregular set of cash flows back to the present to compare one course of action with another. Such problems appear throughout the MBA curriculum.
  • Time Value of Money
    • Annual Compounding
      • Present Value
      • Rate
      • Number of Periods
      • Future Value
    • Sub-Annual Compounding
      • same as Annual plus:
      • Periods per Year
  • Annuities and Perpetuities
    • Constant
    • Growing
  • Bond Basics
    • Zero Coupon
    • Coupon
  • Net Present Value

Accounting

Making sense of accounting requires a clear understanding of the three main financial statements and how these statements represent standard business transactions. The math is simple. The challenge lies in the logic, definitions, and conventions. Using Intel's financial statements as an example, you learn the basics about the balance sheet, income statement, and statement of cash flows.

After studying each financial statement separately, you then work on the connections among the three statements with a set of examples.

You use the balance sheet equation and t-accounts to characterize standard business transactions in terms of offsetting debits and credits . Finally, you apply what you learned with t-accounts to make appropriate journal entries.
  • Balance Sheet
    • Assets
    • Liabilities
    • Equity
    • Balance Sheet Equation
    • Transactions
  • Income Statement
    • Revenues
    • Expenses
    • Cash vs. Depreciation
  • Statement of Cash Flows
    • Operating Activities
    • Investing Activities
    • Financing Activities
    • Cash vs. Depreciation
  • T Accounts and Balance Sheet Equation
    • Balances
    • Debits
    • Credits
    • Transactions
  • Journals
    • Journal Entry Template
    • Debits
    • Credits
    • Transactions

Microeconomics

Marginal analysis addresses the question of how much to produce to maximize profit, given specified costs and revenues. Problem statements and solutions involve either tables or formulas. You learn to distinguish among marginal, total, and average costs and revenues.

Supply and demand are the classic economics concept. You learn to create and interpret the classic linear "curves", compute the equilibrium point that maximizes profit and the corresponding consumer surplus. You examine market segmentation, and use demand curves as part of marginal analysis.
  • Marginal Analysis
    • Tables
    • Formulas and Calculus
  • Supply and Demand

Statistics and Probability

You start with basic summary statistics, which form the foundation. You then tackle statistics of linear combinations, which is a fancy way of saying stock portfolios.

Tables and graphs summarize raw data. You need to know how to make them and work with them.

Regression allows you to draw a best-fit line through a set of data points. You can do it visually or computationally. Both approaches are a snap using Excel.

The standard normal "bell curve" is the king of continuous distributions. You learn to work with continuous distributions in terms of intervals rather than points. Excel makes solutions a breeze but you may, depending on your MBA program, need to learn the z-table approach and its corresponding pictographs and conversions.

Sampling and inference extend the normal distribution to the Central Limit Theorem, confidence intervals, and hypothesis testing.
