Our standards
Editorial Policy
Clear Math Kit exists to make everyday calculations easier to understand. Usefulness, accuracy, and plain language come before search traffic or advertising.
How content is created
Each guide starts with a specific question a reader may genuinely need to answer. We explain the relevant formula, work through realistic examples, identify common mistakes, and link to a calculator only when it helps complete the task.
How calculations are checked
Formulas are tested with known values, boundary cases, and a second manual calculation. We distinguish similar concepts—such as margin and markup or percentage points and percent change—rather than treating them as interchangeable.
Human review and automation
Tools may assist with drafting, editing, or consistency checks, but material is reviewed for mathematical accuracy, originality, usefulness, and tone before publication. We do not publish unreviewed mass-generated pages or copy other publishers’ work.
Updates and corrections
Evergreen guides are reviewed when formulas, examples, wording, or reader feedback reveal a reason to improve them. We do not change dates merely to make old content appear new. If you find an error, send the page address and a clear description through our contact page.
Advertising independence
Advertising supports free access but does not decide our conclusions, examples, or recommendations. Ads are labelled and kept separate from calculator controls and editorial links. Advertisers do not receive advance review of our content.
Scope
Our calculators and guides provide general educational information. They are not financial, tax, legal, medical, accounting, or other professional advice. Important decisions should be checked against authoritative sources or a qualified professional.
