About Math

Mathematical calculators for students, professionals, and anyone solving real problems — scientific, percentage, GPA, statistics, fraction, ratio, quadratic equation, trigonometry, logarithm, permutation/combination, and more. Each tool shows the formula and the step-by-step derivation, not just the answer.

Whether you're studying for a calculus exam, computing batch standard deviation for a quality-control report, solving a Class 10 quadratic, or just need a 25% tip split among 6 people — these tools give you the math AND the working, so you can learn from each calculation.

Step-by-step working

Every result shows the formula used and the substitution, so you can check (and learn from) each step.

Pakistani GPA scales

Supports HEC 4.0, percentage, and grade-letter conversions used by Pakistani and South Asian universities.

Scientific + everyday

From basic percentage and ratio to logarithms, trigonometry, and statistics batch processing — one consistent UI.

Frequently Asked Questions

Do these tools show the formula and working?

Yes — every calculator displays the formula, the substitution with your values, and the step-by-step result. Perfect for school/college work where you need to show your math.

Which GPA scale does the GPA calculator use?

It supports the HEC Pakistan 4.0 scale (default), 5.0 scale, percentage-to-letter, and custom scales. Switch via the dropdown at the top of the calculator.

Can I compute statistics on a large dataset?

Yes — the Statistics Batch Calculator accepts up to 10,000 numbers (paste from spreadsheet) and computes mean, median, mode, range, variance, and standard deviation in one pass.

Are the answers exact or rounded?

Internally the math is computed to full IEEE 754 double precision (~15-17 significant digits). The display rounds to a sensible number of decimals — usually 2-6 — but you can see the full precision by hovering or copying.
