What this scientific calculator can do
Unlike a basic calculator, a scientific calculator understands function names, parentheses and powers. This one accepts inputs such as:
sin(30)+2^3(in degrees)ln(5) + sqrt(2)(3+4)*55!(factorial)
You can also type directly in the display using your keyboard – helpful on desktop.
