Know this first
Mathematics problems are solved by expressing every condition precisely before transforming, counting or taking a limit.
Constraint · A condition every valid result must satisfyDomain · The allowed values for variables

Find the tested idea
Translate the wording into variables, a diagram or an explicit sequence before manipulating it.
Build the solution
Use one justified identity, limit, counting rule or probability relationship at a time. Preserve the domain and all restrictions.
Verify before choosing
Return to the exact wording and check that the result satisfies every stated condition, definition and unit.
OlympIQ exam lens
- ✓State the variables and restrictions.
- ✓Apply one exact relation at a time.
- ✓Check the final result in the original form.
OlympIQ trap
A neat transformation is not enough—substitute or test the conclusion against the original condition.
