How to Use Math101

Use Math101 through the cycle **locate → learn → attempt → diagnose → revisit**.

Open the full lesson →
Use Math101 as an active study loop: locate a precise skill, learn its meaning, attempt practice, diagnose errors, and revisit after a delay.

Intuition and core definition

Use Math101 through the cycle locate → learn → attempt → diagnose → revisit. Locate one narrow skill; learn its meaning and conditions; attempt without support; diagnose the first gap; and revisit after time has passed. The site is designed for active use, so scrolling through a lesson is preparation, not completion.

Notation, language, and conditions

A prerequisite is a skill required before the present method makes sense. A worked example demonstrates reasoning; practice asks you to reproduce that reasoning independently. A check uses the original relationship to test an answer, while an answer key reports an outcome and a brief route. These terms describe different jobs and should not be collapsed into “looking at solutions.”

Why this idea matters

An active lesson cycle turns reading into evidence: an independent attempt reveals whether the idea can be recalled, applied, and checked without a model in view.

A dependable method

  1. Write a one-sentence target beginning “I can…,” for example, “I can convert degrees to radians.”
  2. Preview headings and identify notation or prerequisite links that are unfamiliar.
  3. Study the core definition and one worked example while explaining why each step is allowed.
  4. Hide the example and complete all three practice items, marking any uncertain line.
  5. Compare with solutions, write one correction, and schedule a short delayed retry.
