General educational information
alaintv provides general instruction in mental arithmetic. Its lessons, examples, and practice questions are for educational and informational purposes only. They are not individualized tutoring, professional advice, a formal qualification, or a guarantee of academic or occupational results.
No guarantee of outcomes
Learning speed differs according to prior knowledge, practice consistency, health, language, environment, and many other factors. Completing stages or timed drills does not guarantee a particular score, grade, job result, memory improvement, or calculation speed.
Timing data should be treated as personal feedback, not a measure of intelligence or worth. Stop or reduce difficulty if timed practice causes distress, and seek appropriate educational support when needed.
Accuracy and verification
We make reasonable efforts to check arithmetic and explain assumptions. Nevertheless, typographical, computational, and interpretive errors are possible. Methods can also be inefficient or unsuitable in particular contexts.
Do not rely solely on alaintv calculations for financial transactions, tax, legal matters, medicine, engineering, navigation, safety, examinations, or other high-consequence decisions. Use qualified advice, official instructions, and independent verification where appropriate.
Money examples are not financial advice
Examples involving prices, discounts, interest, tax, tips, wages, or budgets exist to teach arithmetic. They do not account for local law, compounding rules, fees, rounding practices, or individual circumstances and are not financial, tax, or investment advice.
External links and advertisements
External links and advertisements can lead to websites controlled by others. alaintv does not guarantee their accuracy, security, availability, privacy practices, or claims. The presence of an advertisement does not constitute an endorsement. Evaluate third-party information before relying on it.
Accessibility and support
Mental calculation is one useful approach, not a requirement for mathematical competence. Learners may appropriately use paper, calculators, assistive technology, extra time, or alternative strategies. The platform is not designed to diagnose or treat learning differences.
Reporting an error
If you believe a lesson or answer is wrong, please send the page address and calculation through our contact page. We welcome specific corrections and review them as promptly as practical.
