Easy-to-use Scientific Calculator with a unique user interface and useful features.

• Calculate expressions containing complex numbers in standard form a+bi and polar (phasor) form r∠(θ).
• Supports all standard mathematical functions plus the Gamma Γ and Psi Ψ functions.

Swipe the number pad to the right to see more functions (trig hyperbolic inverses etc).

• RAD and DEG mode.
• Fixed scientific and engineering notations.

Do statistics with one or two dimensional data:
• x1 x2 x3 ....
• Press Σ to calculate sum mean max min variance sample and standard deviation medianupper and lower quartile etc.

• x1 y1; x2 y2; x3 y3; ... .
• Press Σ to calculate the equation of the linear regression line and graph it .

• Long press ! to calculate combinations C(n r) and permutations P(n r).

• Enter functions f(x) or parametric equations p(t) and generate table of values.

• Physical/Chemical/Atomic and other scientific constants.

• Easy to use unit converter. (Time Mass Length Velocity and many more.)

All of the above with more details are included in the built-in Instruction menu accompanying this scientific calculator.
