Approximated formulas for a basic calculator (addition, multiplication and division):

θ(deg) = 172*a/(b+2*c)

θ(rad) = 3*a/(b+2*c]

where:

θ the smallest angle in a right triangle

a the smallest right side

b the other right side

c the hypotenuse

Every living thing has no choice but to execute its pre-programmed instructions embedded in it (known as instincts).

But only a human may have the freedom and ability to oppose his natural robotic nature.

But, by opposing it, such a human becomes no more of this world.
