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.
