IB Math AI Formula Booklet: What You Need to Know

The IB Math AI formula booklet is one of the most useful tools students have during their exams. Some IB classes require a lot of memorization like chemistry and biology, but IB math is more about applications of skills. The formula booklet supports this by providing key formulas for topics such as algebra, statistics, calculus, and finance.

Often the students do not have the habit of going directly to the formula booklet. While it contains essential formulas, it does not include everything you need to succeed.

For example, students are expected to understand concepts like outliers. The rule is that an outlier is any value below
Q1 − 1.5 × IQR or above Q3 + 1.5 × IQR.
This is not explicitly explained in the booklet—you must know how and when to apply it.

There are other things that are not in the formula booklet as well:

  • Definitions (e.g., mean, median, variance, standard deviation)
  • When to use specific statistical tests or distributions
  • Interpretation of graphs (e.g., recognizing skewness or correlation)
  • Financial math concepts like compound interest and annuities (beyond just plugging into formulas)
  • How to recognize the 4 criteria of binomial theorem which are:

Key Conditions (BINS):

  • B – Binary Outcomes: Each trial must result in exactly two outcomes: “success” or “failure” (e.g., yes/no, win/loss).
  • I – Independent Trials: The outcome of one trial must not affect the outcome of any other trial
  • N – Number of Trials Fixed: There is a fixed, finite number of trials.
  • S – Same Probability: The probability of success, denoted by must be the same for each trial.

Another critical area is graphing calculator skills. IB math can use the graphing calculator a lot and students are allowed to use the graphing calculator for all papers in IB AI math:

  • Use functions like regression and statistical tests
  • Work with normal and binomial distributions
  • Interpret outputs correctly (not just compute them)

In short, the formula booklet is great and has good information and it is important for the students to go through the formula booklet to know exactly what is in there and what is not. Success in IB Math AI comes from understanding concepts, practicing exam-style questions, and mastering your calculator.
