The same color buttons are a pair of inverse operators, its result can be checked each other if it returns origial function or not. Usual keywords are lowercase, which are different from uppercase, e.g. sin is different from Sin. Its default variable is small letter x, but its default index variable in discrete math is k.

Example:

Add new function f(x) = `x^2`; call f(2)
f(x) = x^2; f(2)

Add new rule of derivative `d/dx` f(x_) := sin(x)
d(f(x_), x_) := sin(x);

Add new rule of integral `int` f(x) dx := F(x)
integrate(f(x_), x_) := cos(x);
