SO FAR, I HAVE FOUND EVERY FORM I NEED. VERY EASY TO NAVIGATE. THE FORMS I NEEDED HAVE REQUIRED ENTRIES AND I WAS ABLE TO COMPLETE THEM. THANK YOU.

Fácil de trabalhar no computador, no celular não gostei muito, as ferramentas não tem a mesma funcionalidade para editação e não tem opção de deixar em português.

Excellent website with great features
I receive documents from my client's customers that need to be filled out and signed by my client. These are handled by PDFFILLER quickly and efficiently.
It's very easy to fill in PDF files and it's just as simple to add and insert signatures.
Sometimes movements within the website are a bit lengthy. After downloading a completed document, returning to the exact page would be nice.

Needed some Quick 1099's - PDF Filler Came to the Rescue
Good product for what it is designed for.
Downloaded this in a pinch when I need to get a vendor a 1099 last minute. Couldn't find anything that would allow me to do this on the IRS website and PDF Filler allowed to complete one in a matter of minutes. Definite a lifesaver and helped me save a relationship with a vendor.
Automatic renewal snuck up on me. I didn't mind paying for it the first year, but this year I didn't need it.

duplicate pages
I like being able to duplicate pages, that was super helpful. It was easy to add the text boxes where I needed them. The only trouble is in downloading the document to my regular google drive. Wish that was more straight forward.

How do you find the sum of a log?
A useful property of logarithms states that the logarithm of a product of two quantities is the sum of the logarithms of the two factors. In symbols, logo(XY)=logo(x)+logo(y). (x y) = log b (x) + log b
What is the log formula?
When we take the logarithm of both sides of ELN(XY)=ELN(x)+LN(y), we obtain LN(ELN(XY))=LN(ELN(x)+LN(y)). The logarithms and exponential cancel each other out (equation (4)), giving our product rule for logarithms, LN(XY)=LN(x)+LN(y).
What is a log rule?
The logarithm of the ratio of two quantities is the logarithm of the numerator minus the logarithm of the denominator. Rule 3: Power Rule. The logarithm of an exponential number is the exponent times the logarithm of the base. Rule 4: Zero Rule. The logarithm of 1 such that b > 0 b > 0 b>0 but b1 equals zero.
What is the addition rule for logarithms?
The rule is that you keep the base and add the exponents. Well, remember that logarithms are exponents, and when you multiply, you're going to add the logarithms. The log of a product is the sum of the logs.
