Use of the tools.
You may use these calculators for lawful study and checking without a fee or account. Output is educational working, not personalised tutoring, grading, certification or professional scientific advice. No teacher, consultant or other advisory relationship is created by using or downloading a result.
Your inputs and conventions.
You are responsible for entering values in the documented formats, selecting the intended operation and checking how signs, powers, zeros, units and rounding are interpreted. A supplied example is not a recommended value or a statement about a real measurement.
Accepted decimal digits are treated as exact mathematical inputs. That is not evidence of physical accuracy. Significant-figure and all-zero counting conventions can differ; use your course or discipline’s requirements.
Limits and independent checks.
The tools implement a documented subset of arithmetic and conversion, subject to input and work-size limits. They do not solve arbitrary expressions, prove theorems, propagate measurement uncertainty or validate a scientific model.
Check important answers independently. Do not rely on the site as the sole basis for safety-critical, engineering, medical, financial or compliance decisions. A readable step-by-step result can still require domain judgement.
Privacy and copies.
Do not enter confidential numbers, account records, student identifiers or private notes. The delivered tools do not save inputs, but browsers, downloads, email, hosting and other installed software may handle data separately as described in the Privacy Policy.
You control any text, PDF or printed copies you create and choose to share. The site does not provide a hosted sharing link or recoverable answer archive.
Availability and acceptable behaviour.
Do not try to disrupt the site, bypass reasonable work limits, inject code or misuse access to the WordPress installation. No guarantee of uninterrupted availability or compatibility with every browser, extension or printer is made.
The tools and explanations may be corrected or changed. Review the current method and settings rather than assuming an old downloaded result reflects a later version.
Content and third-party services.
The site’s original explanations and interface are supplied with the plugin; its code is distributed under the included GPL licence. Those terms do not grant rights to third-party trademarks or imply endorsements.
Any services added by the operator have their own terms and privacy behaviour. The plugin does not itself sell tutoring, fetch live data or offer an official scientific service.
Local law and contact.
These conditions do not exclude mandatory consumer or other rights that cannot lawfully be excluded. The operator should obtain appropriate legal review for its identity, jurisdiction and actual services rather than treating this general text as a complete legal determination.
