Although I do find it a bit difficult to find some of the forms that I am searching for I do like the program completely because it offers me the flexibility to take care of my business and to edit the necessary forms needed for my work. But I wish you would get a larger database of forms and templates for us to draw upon.

Logarithm power rule. Logb(x y) = y A logo(x)
Logarithm base switch rule. Logb(c) = 1 / logic(b)
Logarithm base change rule. Logb(x) = logic(x) / logic(b) Logarithm — log(x) See also.
