Scientific Calculator Functions
Is this calculator good for exams?
This tool is for practice and homework. For formal exams, use a permitted physical calculator. Check your institution's allowed materials list.
Does it use degrees or radians for trig?
The calculator uses degrees by default — the most common choice for academic work. Radians are available via the Rad/Deg toggle.

Is this calculator allowed in university exams?
Most formal exams require a physical calculator. This web-based tool needs an internet connection so it is suitable for homework, assignments, and open-book assessments only. Check your specific exam regulations — some allow any non-CAS calculator, others specify approved models.
Does this support degrees and radians?
Yes. Toggle between DEG and RAD modes before performing trigonometric calculations. If your trig results look wrong, check that you are in the correct angle mode — this is the most common source of error.
How do I calculate combinations nCr for statistics?
Enter the value of n, press the nCr button, enter the value of r, then press equals. For example to calculate C(10,3): enter 10, press nCr, enter 3, press equals — the result is 120.
