This CalcSolver calculator handles arithmetic, powers, roots, trigonometric functions, and logarithms. Use the Code Mode toggle when you want to enter a 4-digit CalcSolver code for games. It does not claim symbolic calculus or step-by-step CAS solving.
Calculator
Code Mode
0
Use degree mode for many geometry problems and radian mode when your course expects radians. Toggle Code Mode above the keypad to type a 4-digit CalcSolver code instead of an expression.
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.
- Opening CalcSolver games with Code Mode and a 4-digit code, including 0000 for the games list.
- 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.
