Frequently asked questions
Degrees or radians?
Choose Degrees for school geometry (sin(30) = 0.5). Choose Radians for calculus work.
Does it follow BODMAS?
Yes. Brackets, orders (powers/roots), division and multiplication, then addition and subtraction.
Is this calculator free to use?
Yes. All MCSBiz calculators are free, work in your browser and need no sign-up.
Is my data stored or sent to a server?
No. Calculations run on your own device. Your inputs are not uploaded, and nothing is saved unless you choose to share a link or export an image.
Can I save or share my result?
Yes. Use "Download PNG" or "Download JPG" to export a snapshot image, copy the result, print it, download a CSV, or copy a link that reopens the calculator with your inputs.
Important note
Results are computed with standard mathematical formulas using floating-point arithmetic and may show tiny rounding differences.
