Calculator

Code Mode
0

Use degree mode for many geometry problems and radian mode when your course expects radians.

Best use cases

  • Checking homework answers after working the problem by hand.
  • Evaluating expressions such as (15 * 4 + 20 / 2).
  • Quick trig or log values without opening a larger app.
  • Verifying percent, loan, and fraction calculations from the other CalcSolver pages.
Examples to try
  • sin(30) in degree mode gives 0.5.
  • sqrt(144) gives 12.
  • log(1000) gives 3.
  • 2^5 gives 32.
