Math Testing
Math testing verifies that software performs mathematical calculations accurately under normal, boundary, and exceptional conditions.
“A test type to determine the correctness of the pay table implementation, the random number generator results, and the return to player computations.”

View the complete ISTQB GlossaryWhat is Math Testing?
It focuses on validating formulas, calculations, numerical precision, rounding behavior, and mathematical algorithms implemented within the application.
Calculation accuracy: Results should match expected mathematical outcomes.
Precision: Floating-point calculations and rounding require careful verification.
Boundary values: Extreme numerical inputs often reveal calculation defects.
Real World Example
A regulated product team is preparing a release where Math testing appears in reviews, test design conversations, or defect triage rather than as an isolated glossary word.
The risk is that the team treats Math testing as interchangeable with nearby ISTQB terms. That makes test scope blurry and can lead to weak evidence for the release decision.
The tester anchors the discussion in the official definition, asks where the concept appears in the product, and designs examples that show the difference between Math testing and similar ideas.
The page becomes useful in practice because Math testing is connected to a specific testing decision, not memorized as a detached definition.
