Math & Education Calculators FAQ
Quick answers to the most common questions.
Which calculator should I use for grades?
Use the Grade Calculator for your current weighted grade, the Final Grade Calculator to see what you need on the final exam, and the GPA Calculator for semester or cumulative GPA.
What’s the difference between log and ln?
ln is the natural logarithm (base e). log often means base 10 (or another base depending on context). Use the Logarithm Calculator to choose any base.
When should I use a t distribution vs a z score?
t distribution is commonly used for smaller samples when the population standard deviation is unknown. Z scores are used when standard deviation is known or samples are large.
What does a p-value tell me?
A p-value estimates how compatible your data is with a null hypothesis. Smaller values suggest the observed result is less likely under the null hypothesis.
Do you have matrix and linear algebra tools?
Yes — you’ll find matrix addition/subtraction, determinants, eigenvalues, and dot product tools in the Linear Algebra section.

How the math and education calculators are organised
The tools on this page follow the order most students meet them: grades and averages first, then algebra, geometry and trigonometry, then statistics and linear algebra, with a set of physics helpers at the end. Every calculator shows its working, so it doubles as a checking tool for homework rather than just an answer machine.
Grades and school
The grade calculator weights assignments and exams into a course grade, the final grade calculator tells you what you need on the exam to reach a target, the GPA calculator handles term and cumulative averages, and the absence percentage calculator tracks attendance against a threshold.
Percentages and numbers
The percentage calculator covers “what percent of”, “percent of what” and reverse percentages, with the percentage change, increase and decrease calculators for comparisons. The fraction to decimal, decimal to percentage, scientific notation, exponential form, hex to binary and Roman numeral converters change how a number is written.
Algebra, logarithms and geometry
The quadratic solver returns real or complex roots with the discriminant shown. The exponent, logarithm, natural log, antilog and growth and decay calculators cover powers and logs. The slope calculator, circumference calculator, sector area calculator, triangle angle calculator and trigonometry calculator handle geometry and trig.
Statistics and linear algebra
The p-value calculator, confidence interval calculator, z-score to percentile calculator, binomial probability calculator and the Student’s t and chi-square distribution calculators cover a first statistics course. The dot product, determinant, eigenvalues, matrix addition and matrix subtraction calculators handle vectors and matrices.
Physics helpers
The speed, velocity, acceleration, kinetic energy, power, centripetal force and projectile motion calculators cover mechanics problems, and the newton-metre calculator and feet to inches calculator deal with units.
Getting the most from them
- Read the steps, not just the answer. Each page shows the formula with your numbers substituted, which is what an exam marker wants to see.
- Match significant figures to the question. The tools show several decimal places; round to what the data supports.
- Use radians where the formula expects them. The trig calculator accepts both, but derivatives and series need radians.
- Check statistical assumptions. A p-value is only meaningful if the test matches the data type and sample size; the pages explain when each test applies.
