The software is very user-friendly and FAST! I have purchased several PDF software programs through the year and many times Nuance Scansoft PDF (ver. 2, 3, 4, 5, 6, 7) and have purchased the Foxit (Phantom PDF) one.
I can say that the ease, the speediness of filling out PDF forms and its online platform make PDF Filler my number ONE PDF software now.
I have only one recommendation. If you could make a tryout period available for the Professional and Business versions, that would be awesome!

A little overwhelming at first. Trying to send to a client to fill out a form but it seems a little difficult. A webinar would be nice. I am going through the FAQ with some success.

What is the log of a number?
The logarithm, or log, is the inverse of the mathematical operation of exponentiation. This means that the log of a number is the number that a fixed base has to be raised to in order to yield the number. Conventionally, log implies that base 10 is being used, though the base can technically be anything.
What is the natural log of a number?
The natural logarithm of a number is its logarithm to the base of the mathematical constant e, where e is an irrational and transcendental number approximately equal to 2.718281828459. The natural logarithm of x is generally written as LN x, loge x, or sometimes, if the base e is implicit, simply log x.
How do you find the natural log of a number?
Calculating the Natural Logarithm with the Log Button Enter the number whose logarithm you need to compute and do not round the number. For example, if you must calculate the natural logarithm of 3.777, enter 3.777 on your calculator. Depress the “Log” button to compute the number's logarithm in base 10.
What is Ln log?
Usually log(x) means the base 10 logarithms. It can, also be written as log10(x). Ln(x) means the base e logarithm. It can, also be written as loge(x). Ln(x) tells you what power you must raise e to obtain the number x. ex is its inverse.
What are logarithms used for?
Logarithms are mainly the inverse of the exponential function. Historically, Math scholars used logarithms to change division and multiplication problems into subtraction and addition problems, before the discovery of calculators.
What are logarithms used for in real life?
Using Logarithmic Functions Much of the power of logarithms is their usefulness in solving exponential equations. Some examples of this include sound (decibel measures), earthquakes (Richter scale), the brightness of stars, and chemistry (pH balance, a measure of acidity and alkalinity).
What is the purpose of logarithmic functions?
Working Definition of Logarithm The purpose of the inverse of a function is to tell you what x value was used when you already know the y value. So, the purpose of the logarithm is to tell you the exponent. Thus, our simple definition of a logarithm is that it is an exponent.
What is a logarithm in simple terms?
A logarithm is the power to which a number must be raised in order to get some other number (see Section 3 of this Math Review for more about exponents). For example, the base ten logarithms of 100 is 2, because ten raised to the power of two is 100: log 100 = 2.
